For each situation described below, describe a possible motion of the turntable. (Some parts have more than one correct answer.) Explain your reasoning in each case.

1. $\stackrel{\to }{a}=0and\stackrel{\to }{a_R}=0$
2. $\stackrel{\to }{a}=0and\stackrel{\to }{a_R}\ne 0$
3. $\stackrel{\to }{a}\ne 0and\stackrel{\to }{a_R}\ne 0$
