A copper block rests a distance r from the center of a steel turntable. The coefficient of static friction between block and surface is μ
a. Please derive an equation for the angular speed w at which the block would slip
and slide off the turntable
= √/r

b. If the copper block is 0.3 m from the center and the coefficient of static friction is
0.53, at what angular speed will it slip and slide off the turntable? (4.16 rad/s)
