) Find the speed at which Superman (mass=90.0 kg) must fly into a train (mass = 17485 kg) traveling at 65.0 km/hr to stop it. Running into the train at that speed would severely damage both train and passengers. (b) Calculate the minimum time Superman must take to stop the train if the passengers experience an average horizontal force of 0.410 their own weight. (c) How far does the train then travel while being slowed to a stop?

A 78.0 kg person falls straight down from a 1.60 m height (measured from his feet) and lands with weight distributed equally on both feet. To soften the blow, he bends his knees so that it takes 0.750s for him to stop once his feet touch the ground. (a) What average force does the floor exert on each foot while he is stopping?(b) Suppose instead that he lands stiff-legged and stops in only 0.100s. What force does the floor now exert on each foot?
