Homework Statement
A projectile of mass m = 1.49 kg moves to
the right with speed v0 = 19.6 m/s. The pro-
jectile strikes and sticks to the end of a sta-
tionary rod of mass M = 6.55 kg and length
d = 2.29 m that is pivoted about a frictionless
axle through its center.
Find the angular speed of the system right
after the collision.
Answer in units of rad/s.
Homework Equations
Icom rod = (1/12)ML^2
3. The Attempt at a Solution [/b
I figured I would use conservation of angular momentum to determine the final angular speed. I'm unsure how to find the initial angular momentum. I can find the final moment of inertia.
(1/12)(1.49 + 6.55)(2.29)^2 = 3.51
