## Homework Statement

A uniform stick 1.0 m long with a total mass of 220 g is pivoted at its center. A 3.2 g bullet is shot through the stick midway between the pivot and one end The bullet approaches at 250 m/s and leaves at 140 m/s

With what angular speed is the stick spinning after the collision?

## Homework Equations

I*wi=I*wf

I of stick = (1/12)ML^2

K= (1/2)(Mb*Vf^2+(1/2)Iw^2

## The Attempt at a Solution

(1/2)*Mb*Vi^2 = (1/2)(Mb*Vf^2+(1/2)Iw^2

i use the above equaltion but it wrong

anyone got any idea how to solve this XD

please help me ^_^
