## Homework Statement

A uniform thin rod (mass 2.74 kg, length 0.934 m) lies motionless on a frictionless, horizontal table. The rod is free to move in any direction on the table. A small block (a point particle of mass = 0.621 kg) slides across the table, moving at right angles to the rod, at speed 4.1 m/s. The block strikes the rod at a distance of 0.11 m below the center of mass, and stops. Assume the block does not stick to the rod

## Homework Equations

vf, the speed of the center of mass of the rod after the collision

## The Attempt at a Solution

I used the conservation of angular momentum:

mv=MV;

mvx=Iw: distance between the point of collison and the center of mass

then solve for V. But it does not seem to give me the right solution.
