Second attempt at solution:
L_{i} = L_{f} + L_{s}
mr^{2}*\frac{v_{i}}{r} = mr^{2}*\frac{v_{f}}{r}
Where the radii are both 0.25m, and the bullet is treated as a point mass. Then,
L_{s} = 2.1875 - 1.4
\frac{mL^{2}}{12}*\omega = .7875
\omega = 31.5
It's wrong, though.
Homework Statement
A uniform stick 1.0 m long with a total mass of 300 g is pivoted at its center. A 3.5 g bullet is shot through the stick midway between the pivot and one end. The bullet approaches at 250 m/s and leaves at 160 m/s. With what angular speed is the stick spinning after the...
