![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 v, = 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 ofhe car is the positive direction. Refer to the figure.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fb6a7c1b7-f35f-47ea-8e6a-769f8780f156%2Fb3c121f5-050a-4528-9a70-4a493bfef039%2Fl9vgkid_processed.jpeg&w=3840&q=75)
