1. The problem statement, all variables and given/known data A solid sphere of mass 1 kg that moves on a level surface at a speed of 20m/s. It then ascends am inclined surface with an angle of 30 degrees. Determine: a) the kinetic energy of the sphere when it is positioned at the base of the inclined surface. b) the distance covered on the inclined surface. 2. Relevant equations What equation should be used here? 3. The attempt at a solution I have no idea how to solve this problem.
