Problem 10: On a one lane road, a person driving a car at v = 78 mi/h suddenly notices a
truck 0.65 mi in front of him. That truck is moving in the same direction at v2 = 41 mi/h. In order to
avoid a collision, the person has to reduce the speed of his car to v2 during time interval At. The
smallest magnitude of acceleration required for the car to avoid a collision is a. During this problem,
assume the direction of motion of the car is the positive direction. Refer to the figure.
