If everyone on the earth lined up around the equator and started running east at 2.5 m/s (EDIT: velocity is relative to surface of the Earth). How much does the length of a day increase? Assume there's $$7x10^9$$ people each with an average mass of $$m_p=55$$ kg. Also, assume the earth to be a solid homogeneous sphere. mass of earth: $$m_e=5.97x10^24$$ kg radius of earth: $$r_e=6.37^6$$ m I understand this is a conservation of angular momentum problem, but I can't seem to get the numbers to work with the answer. Could someone give me some guidance?
