The wrecking ball weighing 1,250 kg is lifted to a height of 12.7 m above its resting point. When the wrecking ball is released, it swings towards the old building and creates a deflection of 43.7 cm in the wall. (A) What is the potential energy of the wrecking ball at a height of 12.7 m? (b) What is the value of the kinetic energy when it hits the wall? (c) If the wrecking ball transfers all of its kinetic energy to the wall, what is the value of the force applied to the wrecking ball to the wall? (d) Why does the wrecking ball hit the wall at the lowest point of its swing?
