A 30.00 kg mass falls from a height of 4.000 m.The momentum of the mass just before it hits the ground is
A) 144.2 kg m/s.
B) 187.8 kg m/s.
C) 320.0 kg m/s.
D) 442.4 kg m/s.
E) 502.1 kg m/s.

The momentum just before hitting the ground is calculated using the formula p = mv, where m is mass and v is velocity. First, find the velocity using v = sqrt(2gh), where g = 9.8 m/s² and h = 4.000 m. Then, multiply by the mass (30.00 kg) to find the momentum.
