1. The problem statement, all variables and given/known data A solid wheel (I = 1/2 MR^2) initially rotating at 5 rad/s comes to a stop after 8 rotations. a) Angular acceleration? b) Tangential accelration at the rim? c) If the mass is 2 kg and the radius is 1.5 m, find the net torque. d) Using values form c, how much energy was required to bring the wheel to a stop? 2. Relevant equations 3. The attempt at a solution a) -24.9 rad/s^2 b) -37.4 m/s^2 c) -56 Nm d) I am not sure how to find the energy used.
