Question

Please solve the following.

The elastic energy stored in your tendons can contribute up to 35% of your energy needs
when running. Sports scientists find that (on average) the knee extensor tendons in sprinters
stretch 43 mm while those of nonathletes stretch only 34 mm. The spring constant of the
tendon is the same for both groups, 33 N/mm.
Part A
What is the difference in maximum stored energy between the sprinters and the
nonathletes?
Express your answer to two significant figures and include the appropriate units.
