Calculate the momentum of 5.07 kg egg that is dropped from a roof and falls 2 seconds before hitting the ground.

Anything that's dropped on or near the Earth accelerates at the rate of

9.8 m/s² on its way down. The mass of the object makes no difference.

After falling for 2 seconds, it's falling at the rate of 19.6 m/s.

Momentum = (mass) x (speed)

The egg's momentum is (5.07 kg) x (19.6 m/s) = 99.4 kg-m/s.
