Physics for Scientists and Engineers 3E by R. Knight, C1E&P17


A toy car rolls down a ramp, then across a smooth, horizontal floor. Draw a complete motion diagram of the toy car.


Solution:

Model

Represent the toy car as a particle.

Visualize

As the toy car rolls down the ramp, its speed increases. This is indicated by the increasing length of the velocity arrows. That is, motion down the ramp is under a constant acceleration \displaystyle \vec{a}. At the bottom of the ramp, the toy car continues with a constant velocity and no acceleration.
