Two Balls and a Thin Rod

Puntos:$20$

Two balls of mass $3\mathrm{.}09$ kg are attached to the ends of a thin rod of negligible mass and length $69$ cm $.$ The rod is free to rotate without friction about a horizontal axis through its center. A putty wad of mass $137$ g drops onto one of the balls, with a speed $2\mathrm{.}3\frac{m}{s},$ and sticks to it$.$ What is the anqular speed of the system just after the putty wad hits?

putty wad

What is the ratio of the kinetic energy of the entire system after the collision to that of the putty wad before the collision $($in percent$)?$

$2\mathrm{.}17$

Incorrecto. Tries $\frac{6}{100}\frac{\text{I}\text{n}\text{t}\text{e}\text{n}\text{t}\text{o}\text{s}}{\text{A}\text{n}\text{t}\text{e}\text{r}\text{i}\text{o}\text{r}\text{e}\text{s}}$
