A person has a mass of 45 kg is running with a velocity of 12.0 m/s. All of a sudden, the person plants their feet and stops abruptly in 3.75 m. This was some mighty agressive stoppage power! Your answer to part (a) may reflect that. a. What was the coefficient of friction between their shoes and the ground in order to do so? b. If it took place in 0.625 seconds how much power was expended by friction on the person?
