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 31 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. ► View Available Hint(s)

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 31 mm.
The spring constant of the tendon is the same for
both groups, 33 N/mm.
