O Bumper- Im Rotation & Energy 15pts A hoop of mass 2kg and radius 30cm is placed on top of an incline, initially at rest. The incline has height of 1.25m and is at a 37 degree angle. Assume the hoop has a moment of inertia of MR2. The bumper and the spring itself are massless. The spring has a spring constant of 40 N/m. (a) What is the linear velocity of the hoop at the bottom of the incline? 5 pts (b) What is the angular velocity at the bottom? 2 pts (c) When the hoop strikes the bumper, how far does it compress the spring? 5 pts (d) Assume that the hoop is stuck to the bumper and it undergoes simple harmonic motion. What is the period of the spring? 3 pts
