A solid uniform ball rolls without slipping up a hill, as shown in (Figure 1). At the top of the hill, it is moving horizontally, and then it goes over the vertical cliff. Neglect rolling friction and assume the system's total mechanical energy is conserved. Figure 1 of 1 25.0 m/s 28.0 m Part A How far from the foot of the cliff does the ball land? Express your answer with the appropriate units. H Value Units Part B How fast is it moving just before it lands? Express your answer with the appropriate units. HA ? v = Value Units
