A bullet of mass 0.01 kg and travelling at a speed of \(500 \mathrm{~ms}^{-1}\) strikes a block of 2 kg, which is suspended by a string of length 5 m. The centre of gravity of the block is found to rise through a vertical height of 0.1 m. The speed of the bullet after it emerges from the block is
- 200 m/s
- 240 m/s
- 220 m/s
- 280 m/s
Answer
(C) 220 m/s
