  1. A Brunswick bowling ball with mass M= 7kg and radius R=0.15m rolls from rest down a ramp without slipping. The initial height of the incline is H= 2m. The moment of inertia of the ball is

    I=(2/5)MR2

    What is the total kinetic energy of the bowling ball at the bottom of the incline?

    684J

    342J

    235J

    137J

If the speed of the bowling ball at the bottom of the incline is V=5m/s, what is the rotational speed ω at the same point?

What is the rotational kinetic energy of the bowling ball KErot at the bottom of the incline?

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...
