Thank you for your help! Should I make a new thread for the second question, then?

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...

Homework Statement The terminal velocity of a 2.8*10^{-5}kg raindrop is about 14 m/s. Determine the time required for such a drop, starting from rest, to reach 63 percent of terminal velocity.Homework Equations F_{g}-F_{D}=-bv The Attempt at a Solution F_{D}=1.96*10\exp{-5} mg-b*(0.63V_{T}) =...
