A 2 kg hoop, with a radius of 0.6 m, is released with backspin onto a 25∘ incline. It is released smoothly, so it does not bounce. The kinetic coefficient of friction between the hoop and the surface is 0.4 and the initial speed of the center of the hoop is 2 m/s up slope, and the initial angular speed of the hoop is 3 rad/s clockwise. a. What are the initial linear acceleration, aC, of the center of the hoop (magnitude and direction)? b. What is the initial angular acceleration, α, the hoop (magnitude and direction)?
