In each situation shown in the figure below, a ball moves from point A to point B. Use the following data to find the change in the gravitational potential energy in each case. You can assume that the radius of the ball is negligible.
(a) h = 1.45 m, θ = 25°, and m = 0.80 kg
J
(b) R = 33.0 m and m = 751 kg
J
(c) R = 33.0 m and m = 751 kg
J
