Chapter 2, Problem 78PQ
Cars A and B each move to the right with constant acceleration along a straight road. The velocity vectors of each car are shown in Figure P2.78 for several times separated by equal time intervals. For the entire interval from time t1 to time t4, car B is ahead of car A (that is, car B is to the right of car A), a. Is the acceleration of car B to the left, to the right, or zero? Explain. b. Is the magnitude of the acceleration of car A greater than, less than, or equal to the magnitude of the acceleration of car B? Explain your reasoning, c. Is the distance between car A and car B at time t3 greater than, less than, or equal to the distance between car A and car B at time t2? Explain.
