A ladder of length L and mass M is leaning against a wall. Assuming the wall and the floor are friction-less, the ladder will slide down the wall and along the floor until the left end loses contact with the wall. Before the ladder loses contact with the wall there is one degree of freedom (θ). Express the kinetic energy in terms of θ and ̇θ.

The elastic energy stored in your tendons can contribute up to 35% of your energy needs when running. Sports scientists have studied the change in length of the knee extensor tendon in sprinters and nonathletes. They find (on average) that the sprinters’ tendons stretch 41 mm, while nonathletes’ stretch only 33 mm. The spring constant for the tendon is the same for both groups, 33 N/mm. What is the difference in maximum stored energy between the sprinters and the nonathletes?
