what is the kinetic energy of a ball with a mass of 5 kg rolling at 10 m/s
If the ball has mass 0.10 kg and it is rolling so that the speed of its center is 0.75 m/s, what is its kinetic energy?i get 0.028 but webassign says my answer is wrong
A bowling ball of mass 5 kg is rolling at a speed of 6 m/s at the bottom of a 30 degree ramp If the ball rolls up ramp w/out slipping, calculate maximum distance ball travels up ramp before it stops and starts rolling back down

Problem -2 A hollow ball of radius 0.5 m and mass 4.5 kg is rolling without slipping on a level surface at a constant speed of 4.0 m/s. The ball rolls up a 40- ramp and eventually stops before rolling back down. (the moment of inertia of a hollow ball of mass M and radius RisMR2) Find: (a) the angular (rotational) speed of the ball (in rad/sec) just before it begins to move up the ramp: (b) the rotational kinetic...
Problem #2 A hollow ball of radius 0.5 m and mass 4.5 kg is rolling without slipping on a level surface at a constant speed of 4.0 m/s. The ball rolls up a 40° ramp and eventually stops before rolling back down.
