A hollow sphere of mass 0.22 kg and radius 0.03 m is rolling across the floor at velocity of 3.8 m/s. It then encounters an incline of θ = 16° when it starts to slow down as it rolls up the ramp. What is the initial angular velocity of the hollow sphere before it starts to decelerate? Considering up the ramp to be the positive direction, what is the magnitude of the linear and angular deceleration as the hollow sphere...
