8. Linear Motion Definitions 

Paul links central kinematic definitions and equations to Barry Biker.

End Question:

Suppose that Barry Biker, with his motor off, coasts down a hill from rest. He moves at a smooth, small, and constant acceleration. In 4 seconds he reaches a speed bump while moving at 12 m/s. What is the distance between his starting point and the speed bump he encounters? In short, how far does Barry travel in 4 seconds?
