A small piece of clay is stuck near the edge of a phonographturntable. Let a represent the angular acceleration of the clay andaR represent the centripetal acceleration of the clay.
For each situation described below, describe a possible motionof the turntable. ( some have more than one correct answer.)Explain your reasoning in each case.
1. a=0 and aR=0
2.a=0 and aR≠0
3. a≠0 and aR≠0
The equation a=aR/r is not a correct vector equation.
1. explain how you can tell that the vector equation is notcorrect.
2. is a=aR/r a correct scalar equation? Explain why or whynot.
