Homework Help: Physics

Posted by JuJu on Sunday, December 4, 2011 at 6:35pm.

A 90 kg person stands on the ground before jumping vertically upward. If momentum is truly conserved in all closed isolated systems, then the Earth-person system should conserve momentum. If the person jumps with a speed of 3.5 m/s, what is resulting speed of the Earth in the opposite direction? (Earth's is approximately 5.96 1024 kg)
