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.
