A plank of length L and mass M hangs from an axle passing through one end. The other end is allowed to hang down so that it just
galben [10]

Answer:

v = ((M(√2gH)/3m)

Explanation:

Initial Moment of Inertia= Moment of Inertia of Rod

I = (ML²)/3

Linear Velocity of moveable end of the rod, just before collision is given by = v = (√2gH)/L

Initial Angular Momentum, about the point of the suspension:

Li= Iw = {(ML²)/3} . {(√2gH)/L} = {ML(√2gH)}/3

Final Angular Momentum = Li = mvl, where 'v' is the speed of the mass 'm' after the collision

Since the collision is elastic, all momentum will be conserved, which means

Initial Angular Momemtum = Final Angular Momentum

{ML(√2gH)}/3 = mvL

solving for v = {(M)/3m} . {(√2gH)/L}
