(a) Find the average torque exerted on the wheel given that it is a disk of radius 0.76 m and mass 6.4 kg.

? N·m

sorry, I'm having converting issues...I don't see the link between theta, omega, moment of inirtia, torque...etc...

- physics 2...help please -
**bobpursley**, Wednesday, October 22, 2008 at 3:42amTorque=momentInertia*deacceleration

The average speed during deacceleration is 1.33/2, so the time to stop is displacement/avg velocity,or .75*2PI/(1.33/2)

deacceleration = wi/time

so you can find torque.
