Question 11

A spring of stiffness $k\,$ is stretched by an extension $e$ . When the stretching force is released, the spring returns to its unstretched length in time $t$ .

What is the average power developed by the spring as it returns to its unstretched length?

$ke2t\frac{k e}{2 t}$

$ke2t\frac{k e^2}{t}$

$ke22t\frac{k e^2}{2 t}$

$k2e2t\frac{k^2 e}{2 t}$
