Part A Use energy to find the ball’s maximum height above the ground. That is, use (1/2)mv^2 = mgy. As you can see, even though you don’t know m, you can divide it on both sides of the equaiton.Express your answer to two significant figures and include the appropriate unitsPart B Use energy to find the ball’s speed as it passes the window on its way down.Express your answer to two significant figures and include the appropriate units.Part C Use energy to find the speed of impact on the ground.Express your answer to two significant figures and include the appropriate units.
