Question:

An animal-rescue plane due east at 50 meters per second drops a bale of hay from an altitude of 62 meters. The acceleration due to gravity is 9.81 meters per second squared. If the bale of hay weighs 191 newtons what is the momentum of the bale the moment it strikes the ground? Answer in units of kilograms times meters per second.

Freefall:

When a rescue plane flying horizontally drops a bale of hay, the bale inherits the horizontal speed of the rescue plane; the vertical velocity increases due to gravity. The momentum on impact equals the product of the mass and the velocity on impact.
