A small coin is placed on a flat, horizontal turntable. The turntable is observed to make three revolutions in 3.14s.

a.) What is the speed of the coin when it rides withoutslipping at a distance of 5.0 cm from the center of theturntable.

b.) What is the acceleration (magnitude and direction) of thecoin?

c.) What is the magnitude of the frictional force acting onthe coin if the coin has a mass of 2.0g?

d.) What is the coefficient of static friction between thecoin and the turntable if the coin is observed to slide off theturntable when it is more than 10cm from the center of theturntable?
