A spherical scientific probe of mass 150 g150\text{ g}150 g is released from rest from a height of 10 m10\text{ m}10 m above a flat concrete testing pad and falls vertically.
The probe collides with the pad and rebounds vertically to a maximum height of 2.5 m2.5\text{ m}2.5 m.
Assume that air resistance is negligible.
What is the magnitude of the change in momentum of the probe during its collision with the pad?
