A thin uniform rod of length l and mass ...

A thin uniform rod of length `l` and mass m is freely pivoted about its end. The rod is initially held horizontally and released from rest. When the rod is vertical, an impulse J is applied to bring it to rest (this is in addition to any impulse provided by the pivot)

The minimum impulse J required to bring it to rest :

A

`m sqrt((gl)/(3))`

B

`2m sqrt((3g)/(l))`

C

`m sqrt((g)/(3l))`

D

`m sqrt((2g)/(3l))`
