Your humble physics Professor elevates a ball hanging from a string away from it's lowest position and holds it there. If she releases it from rest, what will be it's change in kinetic energy when it reaches the bottom of it's swing? 100 J Not enough information to answer this question 50 J 105 J Your humble physics Professor elevates a ball hanging from a string away from it's lowest position and holds it there. It requires 105 J of Energy to do this. If the ball has a mass of 30 kg, then how far up did the physics professor raise the rock? 0.36 m 0.16 m not enough information is given to answer this question 0.26 m
