Start with a freely rotating hoop-like wheel of mass m = 30kg and radius 25cm, rotating at 125 rpm.1. Sketch this wheel, write out equations for and calculate it’s L and rotational KE.The wheel hits the ground, bounces and skids while negative accelerating, eventually locking to the ground so that its linear velocity equals its rotational velocity times its radius.2. Write this (roll no slip) equation. Sketch this final rolling wheel on the ground, include a vector for the linear velocity.3. Write an equation conserving angular momentum before and after the drop. Solve your equation for final angular velocity (both algebra and a number). Briefly explain.4. Solve for final rotational and linear kinetic energy and compare to initial rotational energy. How much energy was lost during the skidding process? (Formula and number).
