heres the problem: A wheel starts from rest and accelerates such
that it's angular velocity increases uniformly to 200rpm in 6s.
After it has been rotating for some time at this speed, brakes
are applied stopping the wheel in 5 min. The total number of
revolutions of the wheel is 3100. what is the total time of
rotation? i have no idea where to start here since the angular
velocity isn't constant the whole time. thanks.
