Distance conveys no information about direction and, hence, is not a vector. The average velocity is the displacement of 0 km divided by the elapsed time. The displacement is 0 km, because the jogger begins and ends at the same place. The change in velocity has a magnitude of Since the change in velocity points due east, the direction of the average acceleration is also due east. Since the average acceleration is the change in velocity divided by the elapsed time, the average acceleration is also zero.

Chapter 2 Answers to Focus on Concepts Questions 43 9. The average velocity is the displacement divided by the elapsed time, and the displacement is zero, since the race starts and finishes at the same place. The average acceleration is the change in the velocity divided by the elapsed time, and the velocity changes, since the contestants start at rest and finish while running.

Velocity is a vector. The magnitude of the instantaneous velocity is the speed. While the rocket is picking up speed in the upward direction, the acceleration is not just due to gravity, but is due to the combined effect of gravity and the engines.

In fact, the effect of the engines is greater than the effect of gravity. Only when the engines shut down does the free-fall motion begin. Therefore, this stone picks up speed as it approaches the nest. In contrast, the acceleration due to gravity points opposite to the initial velocity of the stone thrown from the ground, so that this stone loses speed as it approaches the nest.

The result is that, on average, the stone thrown from the top of the cliff travels faster than the stone thrown from the ground and hits the nest first. The slope for part A is positive. For part B the slope is negative. For part C the slope is positive. Section A has the smallest slope and section B the largest slope. Here the slope is positive at all times, but it decreases as time increases from left to right in the graph. This means that the positive velocity is decreasing as time increases, which is a condition of deceleration.

The number of football fields is equal to this distance divided by the length L of one football field. If the final position is greater than the initial position, the displacement is positive.

On the other hand, if the final position is less than the initial position, the displacement is negative. Since the average speed and distance are known, we can use this relation to find the time. The displacement is equal to the difference between the final and initial positions.

Distance is a scalar, and displacement is a vector. Distance and the magnitude of the displacement, however, are both measured in units of length. The distance traveled is equal to three-fourths of the circumference of the circular lake. REASONING The younger and faster runner should start the race after the older runner, the delay being the difference between the time required for the older runner to complete the race and that for the younger runner.

The time for each runner to complete the race is equal to the distance of the race divided by the average speed of that runner see Equation 2. From Equation 2. The total displacement traveled by the bicyclist for the entire trip is equal to the sum of the displacements traveled during each part of the trip.

The displacement traveled during each part of the trip is given by Equation 2. The average velocity can be found from Equation 2. The displacement in this expression is the total displacement, which is the sum of the displacements for each part of the trip.

Displacement is a vector quantity, and we must be careful to account for the fact that the displacement in the first part of the trip is north, while the displacement in the second part is south. Note that the minus sign indicates a direction due south. The time required for the train to travel 6. Since the direction of travel is in the negative direction throughout the problem, all velocities will be negative.

The change in velocity is equal to the final velocity minus the initial velocity. Therefore, the change in velocity, and hence the acceleration, is positive if the final velocity is greater than the initial velocity. The acceleration is negative if the final velocity is less than the initial velocity. The acceleration is zero if the final and initial velocities are the same. REASONING Although the planet follows a curved, two-dimensional path through space, this causes no difficulty here because the initial and final velocities for this period are in opposite directions.

Thus, the problem is effectively a problem in one dimension only. It will be convenient to convert the elapsed time to seconds before calculating the average acceleration. For convenience, we will choose them to be positive. The velocity, acceleration, and the time are related by Equation 2. Solving Equation 2. When the velocity and acceleration vectors are in opposite directions, the speed of the object decreases in time.

The final velocities and speeds for the four moving objects are: a. The final speed is 6. The initial velocity of the emu is directed due north. Since the bird is slowing down, its acceleration must point in the opposite direction, or due south. We assume that due north is the positive direction. With the data given for the first part of the motion, Equation 2. The magnitude of the acceleration can be found from Equation 2.

Assuming that the acceleration is constant, the displacement covered by the car can be found from Equation 2. We can find the elapsed time from this relation because the acceleration and the change in velocity are given. Therefore, Equation 2. With x representing the displacement traveled along the slope, Equation 2. The actual time required for Secretariat to run the final mile can be determined from Equation 2.

It is the difference between these two results for the time that we seek. The acceleration allowed Secretariat to run the last mile in a time that was faster by In other words, the cart is decelerating, and its acceleration must point opposite to the velocity, or to the left.

Thus, the acceleration is negative. This occurs, because each rocket is decelerating during the first half of its journey. Chapter 2 Problems 59 However, rocket A has a smaller initial velocity than rocket B. Therefore, in order for rocket B to decelerate and return to its point of origin in the same time as rocket A, rocket B must have a deceleration with a greater magnitude than that for rocket A. Since we know that the displacement of each rocket is zero at time t, since both initial velocities are given, and since we seek information about the acceleration, we begin our solution with Equation 2.

First, there is the distance the car travels at According to Equation 2. Second, there is the distance the car travels while it decelerates as the brakes are applied. This distance is given by Equation 2. Since it is decelerating, its acceleration points opposite to its velocity. This velocity is found from Equation 2. Since both cars begin and end the interval side-by-side, they both undergo the same displacement x during this interval.

The displacement of each car is given by Equation 2. For convenience, we will place the origin at the starting point of the first player. This is also the travel time for the second car to reach the next exit. The acceleration for the second car can be determined from Equation 2. This equation applies, because the acceleration is constant.

None of these four equations contains all three known quantities and the desired displacement x, and each of them contains the initial velocity v0. Since the initial velocity is neither known nor requested, we can combine two kinematic equations to eliminate it, leaving an equation in which x is the only unknown quantity. Once v is known, Equation 2. Since the train starts from rest with a constant acceleration, the displacement of the train in a time t is given by Equation 2.

The final speed can be found from Equation 2. In a , we will consider the interval beginning at launch and ending 2. In b , we will consider the interval beginning at launch and ending 5. Therefore, we may use Equation 2.
