Q. If the ball is free from rest at a height of 0.8 above the bottom of the track on the no-slip side, what is its angular speed while it is on frictionless side of the track? Suppose the ball is a solid sphere of radius 2.3 and mass 0.14.
Q. A car of mass = 800 travelling at 45.0 enters a banked turn covered with ice. The road is banked at an angle, and there is no friction between the road and the car's tires. What is the radius of the turn if = 20.0 (Assume the car continues in uniform circular motion around the turn)?
