A car traveling at a speed of 13 meters per second accelerates uniformly to a speed of 25 meters per second in 5.0 seconds. A truck traveling at a constant speed covers the same total distance as the car in the same 5.0 second interval.

A record of travel along a straight path is as follows: (a) start from rest with constant acceleration of 2.62 m/s 2 for 12.8 s; (b) constant velocity of 33.536 m/s for the next 0.895 min; (c) constant negative acceleration of - 11.2 m/s 2 for 5.
