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)
What is the angular velocity of the rod at the moment it reaches the vertical position ?
A. `sqrt((6g)/(l))`
B. `2 sqrt((3g)/(l))`
C. `sqrt((3g)/(l))`
D. None of these
