**1. The problem statement, all variables and given/known data**

A rod of length L and mass M is pivoted at the center C such that it can freely rotate in vertical plane.Initially the rod is at horizontal position.A blob of wax of mass M falls vertically with speed V and sticks to the rod midway between center and one end.If the rod rotates with angular speed ω what will be the angular velocity in terms of V and L?

**2. Relevant equations**

none

**3. The attempt at a solution**

Can i use energy conservation here.The kinetic energy carried by the wax blob will be transferred into rotational energy.Is this approach right?
