1. A 5.40 g coin is placed 17.0 cm from the center of aturntable. The coin has static and kinetic coefficients of frictionwith the turntable surface of μs = 0.810 and μk = 0.460.
Part A: What is the maximum angular velocity with which theturntable can spin without the coin sliding? Express your answerwith the appropriate units.
2. A 800 g ball moves in a vertical circle on a 1.09 m -longstring. If the speed at the top is 4.30 m/s , then the speed at thebottom will be 7.82 m/s .
Part A: What is the ball's weight? Express your answer with theappropriate units.
Part B: What is the tension in the string when the ball is atthe top? Express your answer with the appropriate units.
Part C: What is the tension in the string when the ball is atthe bottom? Express your answer with the appropriate units.
