A bouncy ball of mass 85.3 grams is dropped from a height of 13.17 meters. It rebound to a height of 5.12 meters. What was the change in momentum (in kgm/s) of the bouncy ball?

Momentum is a measure of an object's motion, calculated by multiplying its mass by its velocity.
When a ball is dropped from a height, its momentum increases as it gains speed due to the force of gravity.
When a ball bounces, its momentum changes direction as it collides with the ground and experiences an equal and opposite force, according to Newton's third law of motion.
The formula for calculating change in momentum is Δp = mΔv, where Δp represents the change in momentum, m is the mass of the object, and Δv is the change in velocity.
The height of the bounce does not affect the change in momentum, as long as the surface the ball bounces on is the same. The change in momentum is dependent on the mass and velocity of the ball.
