A solid sphere of mass 0.524 kg rolls without slipping along a horizontal surface with a translational speed of 5.33 m/s. It comes to an incline that makes an angle of 31.7° with the horizontal surface. Ignoring energy losses due to friction, to what vertical height above the horizontal surface does the sphere rise on the incline?
