Homework Statement
There is a small block of steel with mass 2.4kg and is firmly attached to a low mass wheel a distance .3m from its center. The wheel is free to rotate about a vertical axis and is at rest. A .0023kg bullet traveling with an initial speed of 305m/s in the horizontal plane strikes the block and bounces off the block and has final speed of 210m/s in the horizontal plane.
Homework Equations
a) what is the angular momentum of the bullet about the center of the wheel just before the collision?
b) what is the rotational speed of the block of steel and wheel just after the collision?
c) how much mechanical energy is lost in this collision?
The Attempt at a Solution
L=r x p
so L=sin(67)(.3)(.0023)(305)?
