A basketball player throws a basketballĀ mĀ = 1 kg straight up with an initial speed ofĀ v0Ā =Ā 9.5Ā m/s. The ball leaves his hand at shoulder heightĀ h0 = 2.2 m.Ā Let gravitational potential energy be zero at ground level.

Part (a)Give the total mechanical energy of the ball E in terms of maximum height hm it reaches, the mass m, and the gravitational acceleration g.

Part (b)What is the height, hm in meters?

Two stones, one with twice the mass of the other, are thrown straight up and rise to the same height h. Compare their changes in gravitational potential energy (choose one): (a) They rise to the same height, so the stone with twice the mass has twice the change in gravitational potential energy. (b) They rise to the same height, so they have the same change in gravitational potential energy. (c) The answer depends on their speed at height h.Ā 

A 1.00 kg ball is thrown directly upward with an initial speed of 16.0 m/s.

A graph of the ball's gravitational potential energy vs. height, Ug(h), for anĀ arbitraryĀ initial velocity is given in Part A. The zero point of gravitational potential energy is located at the height at which the ball leaves the thrower's hand.

For this problem, take g=10.0m/s2 as the acceleration due to gravity.

Draw a new gravitational potential energy vs. height graph to represent the gravitational potential energy if the ball had a mass of 2.00Ā kg. The graph for a 1.00-kg ball with anĀ arbitraryĀ initial velocity is provided again as a reference.
