The length of ballistic pendulum is 1 m ...

The length of ballistic pendulum is `1 m` and mass of its block is `0.98 kg`. A bullet of mass `20` gram strikes the block along horizontal direction and gets embedded in the block. If block + bullet completes vertical circle of radius `1m`, then the striking velocity of bullet is

A

`280 m/s`

B

`350m/s`

C

`420 m/s`

D

`490 m/s`

Text Solution

Verified by Experts

The correct Answer is:
`(2)`
According to law of conservation of linear momentum mu = (M + m)v
`u = (M + m)sqrt(5gr)/m`

The length of a ballistic pendulum is 1 m and mass of its block is 1.9 kg . A bullet of mass 0.1 kg strikes the block in horizontal direction with a velocity 100 ms^(-1) and got embedded in the block. After collision the combined mass swings away from lowest point. The tension in the strings when it makes an angle 60^@ with vertical is (g=10 ms^(-2)) .
