Academics

A fly wheel turns through 30 rev(1 rev=2pie rad) as its slows from an angular speed of 6 rad/s to a stop.

a. Assuming a constant angular acceleration, find the time for it to come to rest.

b. Calculate the angular acceleration.

c. How much time is required for it to complete the first 15 of the 30 revs?
