An example of a system with decreasing gravitational potential energy is a ball in free fall.
At its initial height h, the ball has a gravitational potential energy equal to
where m is the ball mass and g is the gravitational acceleration. As the ball falls toward the ground, its height h decreases, and so its gravitational potential energy decreases as well, according to the formula
where h' is the new height of the ball.

Answer:1.549 kg-m/s
Explanation:
Given
mass of basketball =609 g
ball is moving downward right at an angle of with vertical
After hitting the floor it moves with a speed of 3 m/s
change in Momentum in x direction
where u=3m/s
v=3m/s
m=mass of ball
Change in momentum in Y-direction
