A pendulum has a cord of 3 meters and a bob weighing 1 kilogram. It is "hit by a child" and rises 2.1 meters. What is the balls Velocity IMMEDIATELY after being hit? What is the balls momentum IMMEDIATELY after being hit? If the child's hand is in contact with the ball for .09 seconds, what is the force with which the childs hand hits the ball? If 10 MORE newtons of force are applied over the same time (0.09 seconds) how high will the ball go?
