That is because you have to use 7/10 instead of 1/2 in the fomula KE=1/2mv^2
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...
A ball of mass 0.10 kg moving with speed 2.0 m/s hits a wall and bounces back with speed 1.0 m/s in the opposite direction. What is the change in the ball’s kinetic energy?
what is the kinetic energy of a ball with a mass of 5 kg rolling at 10 m/s
A bowling ball of mass 4.5 kg is rolling at a constant speed of 1.35 m/s. It rolls at this speed for 3.20 s and for a distance of 4.32 m. What is the net force acting on the bowling ball during this time? Give your answer in newtons.
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
Ball A, rolling west at 3.2 m/s, has a mass of 1.0 kg. Ball B has a mass of 2.4 kg and is stationary. After colliding with ball B, ball A moves south at 2.0 m/s.

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. (the moment of inertia of a hollow ball of mass M and radius R is MR2) Find: (a) the angular (rotational) speed of the ball (in rad/sec) just before it begins to move up the ramp; (b) the...
A ball of mass 0.170 kg moving with speed 2.22 m/s hits a wall and bounces back with speed 1.00 m/s in the opposite direction. What is the change in the ball’s kinetic energy? Answer ___J
A solid metal ball is rolling with a linear speed of 2.5 m/s at the bottom of a hill. The ball starts to roll up the hill. If the ball has a mass of 5.00 kg and a radius of 10.0 cm, what vertical height will the ball roll through before its speed has been cut in third, assuming it rolls without slipping?
