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 42 mm while those of nonathletes stretch only 35 mm. The spring constant of 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? Express your answer to two significant figures and include the appropriate units. ▸ View Available Hint(s) |ī| μA N ?

Transcribed Image Text: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 42 mm while those of nonathletes stretch only 35
mm. The spring constant of 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?
Express your answer to two significant figures and include the appropriate units.
