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. Determine the speed of the truck.

Calculate the magnitude of the accelerate of the car during this 5.0 second interval.

Solis · Answer 1

A. (change in speed) / time

So,

=25m/s^2/5s

=5 m

b. That means the truck has the same average speed. In the case of constant acceleration, average speed = average of initial and final speeds = average of 13m/sec and 25 m/sec.
