One end of a spring is tied to a wall and the other end moves at speed $v$ . If the mass of the spring is $m$ , its kinetic energy is:

Options:

Answer:

Solution:

An element at distance $s$ from the wall (length $l$ ) moves at $v s / l$ . $K E = \int \frac{1}{2} \frac{m}{l} \frac{v ^{2} s ^{2}}{l ^{2}} d s = \frac{1}{6} m v^{2}$ .
