Please attempt this question first.
A block of mass \(m\) is moving with initial velocity \(u\) towards a stationary spring of stiffness constant \(k\) attached to the wall as shown in the figure. Maximum compression of the spring is:
(The friction between the block and the surface is negligible).
| 1. | \(u\sqrt{\frac{m}{k}}\) | 2. | \(4u\sqrt{\frac{m}{k}}\) |
| 3. | \(2u\sqrt{\frac{m}{k}}\) | 4. | \(\frac12u\sqrt{\frac{k}{m}}\) |
