Question

Nutso the Clown has a new routine. He gets inside a large hoop and begins rolling with an initial angular velocity that is just large enough so that he does not fall from the hoop's edge. He begins rolling at this angular velocity at a height of 23 m. Consider his mass (73 kg) and the hoop's mass (21 kg) as located entirely at the hoop's radius of 0.62 m. The end of the ramp is inclined upward at 22 degrees and is located at a height of 1.6 m. After leaving the ramp, the rotational velocity can be treated as a constant. What is the speed when Nutso and the hoop hit the pavement at ground level?
