The friction coefficient bettween an athelete's shoes nd the ground is 0.90. Supose a superman wears these shoes and rces for 50 m. There is no upper limit n his capacity of running at high speeds. A. Find the minimum time tht he will have to take in completing the 50 m starting from rest. b. Suppose he takes exactly this minimum time to complete the 50 m, what minimum time will he take to stop?
