If a 0.14-kg baseball is dropped from rest from a height of 2.0 m above the ground, then the magnitude of its momentum just before it hits the ground would be  0.8764 kg - m / s.

What is momentum?

It can be defined as the product of the mass and the speed of the particle, it represents the combined effect of mass and the speed of any particle, and the momentum of any particle is expressed in Kg m/s unit.

As given in the problem if a 0.14-kg baseball is dropped from rest from a height of 2.0 m above the ground.

The velocity just before hitting the ground = √ ( 2 × 9.8 × 2)

                                                                      = 6.26 m / s

The magnitude of its momentum just before it hits the ground = 0.14 × 6.26

= 0.8764 kg - m / s

Thus, the magnitude of its momentum just before it hits the ground would be  0.8764 kg - m/s
