A lead pellet is fired straight upward into a clay block, which is at rest at the instant of collision but can move upward without restriction after the impact. The pellet strikes the block with an initial velocity of $200\,\text{m s}^{-1}$. It becomes lodged in the block and does not pass back out. To what height above its starting point does the block climb? (Mass of pellet $= 5.0\,\text{g}$; mass of clay block $= 95\,\text{g}$.)
- A$5.1\,\text{m}$
- B$5.6\,\text{m}$
- C$10\,\text{m}$
- D$2000\,\text{m}$
