Consider the car driving around a circular track. once started, the driver maintains a speed of 45 m/h. compare the driver's velocity with his acceleration in this case.
a) the car is accelerating because it is changing direction but the velocity is constant.
b) the car is traveling at a constant rate of speed so it is not accelerating and the velocity does not change.
c) acceleration is the change in velocity so the car is experiencing a change in velocity and it is accelerating.
d) the car is traveling at a constant rate of speed so it is not accelerating but the velocity changes because the direction the car travels is constantly changing.
