Suppose that all people got together and jumped up simultaneously. Assume that an average mass of a person is 50 kg, the average height of a jump is 0.5 m and the jump interval (from lowering the body to the feet taking off) lasts for 0.3 s. The mass of Earth is 6 x 1024 kg. Note that the world has approximately 7 billion people. Part A Estimate how much Earth would move due to the jump. Express your answer with the appropriate units. H ? d = 5.4812 10 - 13 m
