A solid ball having a mass of 2.6 kg and a radius of 0.2 m is placed at the top of an incline. The height of the incline is 3.0 m. The ball is then released and rolls without slipping down the incline. The translational velocity of the ball at the bottom of the incline is

Question

Quizplus · Accepted Answer

The potential energy at the top is converted into translational and rotational kinetic energy at the bottom. Using energy conservation and the moment of inertia for a solid sphere, the translational velocity is calculated to be approximately 6.5 m/s.
