# Handle the putty wad with care!

The $2.00 kg$ balls are attached to the ends of a thin rod of length $50.0 cm$ and negligible mass. The rod is free to rotate in a vertical plane without friction about a horizontal axis through its centre . With the rod initially horizontal, a $50.0 g$ wad of wet putty drops onto one of the balls, hitting it with a speed of $3.00 m/s$ and then sticking to it. Through what angle (in degrees) will the system rotate before it momentarily stops?
