A bowling ball is placed at the top of an incline and released so that it rolls, without slipping, down the hill. Which of the following are true? (Select all that apply.)
The bowling ball's velocity is changing, therefore its acceleration is changing.
The bowling ball is getting faster as it rolls downhill.
The bowling ball is experiencing an increase in its total energy as it rolls down the hill.
The bowling ball is experiencing linear acceleration.
The bowling ball is experiencing angular acceleration.
