Question

A 2kg ball moving at 2m/s is rolling towards an inclined plane (Point A). It eventually rolls up the hill to a position near the top where it momentarily stops prior to rolling back down the incline. Assume negligible friction and air resistance.Determine how high up the ramp the ball gets before coming to a stop (Point B).

Answer 1

\[KE _{i} + PE _{i} + W _{ext} = KE _{f} + PE _{f}\]
