Solve the all parts of given problem:
Problem: A coin sits on a rotating turntable at a distance of 8 cm from the center of the table. When the turntable spins at 33 rmp, the coin just barely stays on the turntable. If the rate of rotation is increased at all, the coin slips off.
Part A: What is the centripetal acceleration of the coin at 33 rmp?
Part B: What is the coefficient of static friction between the coin and the turntable?
Part C: If the coin is moved to a location that is 4 cm from the center of the turntable, what is the new maximum rate of rotation (in rpm) at which the coin will stay on the table? You don't have to use your answer from part (B) here; remember that centripetal acceleration can be written ac=w2r.
I want you to clarify the physics in this above problem.
