a) What is the maximum torque exerted by a 60 kg person riding a bike, if the rider puts all his weight on each pedal when climbing a hill? The pedals rotate in a circle of radius 17
b) A ball of mass 1.5 kg rolling to the right with a speed of ,6.31ms−1 collides head-on with a spring with a spring constant of .0.22Nm−1 Determine the maximum compression of the spring and the speed of the ball when the compression of the spring is 0.10 m
