The 75 kg man is falling at 15 m/s! In an attempt to stop his fall, the brake shoe is pressed against the spinning pulley with a force of 1000 N. The coefficient of friction between the brake shoe and the pulley is (0.9,0.8) and the 35 kg disk shaped pulley has an inner and outer diameters of 0.6 m and 0.9 m
a) how long does it take to stop the man's fall.
b) how far does this man fall.
