A wooden block of mass `0.9 kg` is suspended from the ceiling of a room by thin wires. A bullet of mass `0.1 kg` moving horizontally with a speed of `10 ms^(-1)` strikes the block and sticks to it. What is the height to which the block rises ? Take `g = 10 ms^(-2)`:

`2.5 m`

`5.0m`

`7.5m`

`10.0m`
