Need a good answer to this question so that i can compare my solutions to yours. A solid sphere with mass of 4.5 kg rolls without slipping on a horizontal plane with a translational speed of its center of mass of 4.8 m/s. It then rolls up an incline with an angle of 30° . a) What is its kinetic energy on the horizontal plane? b) How far does the sphere travel up along the incline? c) How high would the sphere travel when its mass would be 9.0kg?
sorry, beyond my capability............
