1) The combination of an applied force and a friction force produces a constant total torque of 35.8 N · m on a wheel rotating about a fixed axis. The applied force acts for 5.90 s. During this time, the angular speed of the wheel increases from 0 to 10.1 rad/s. The applied force is then removed, and the wheel comes to rest in 60.1 s. (a) Find the moment of inertia of the wheel.   kg · m2 (b) Find...

A bowling ball (solid sphere, moment of inertia is (2/5)MR2) of mass M and radius R rolls down a hill without slipping for a distance of L along the hill with slope of angle θ, starting from rest. At that point, the hill becomes frictionless.The ball continues down the hill for another segment of length 2L (thus the total distance travelled on the hill is 3L). The hill levels out into a horizontal area, where the coefficient of friction is...
