# Calculate the angular momentum

**1. The problem statement, all variables and given/known data**

A batter swings a 0.9 m long bat. Calculate the angular momentum of the bat relative to its axis of rotation. Assume the bat has a mass of 0.6 kg and rotates at 3 rad / s

(Hint: Approximate the bat by a rod, or a long thin cylinder, and find the moment of inertia.)

Answer in (N m)

**2. Relevant equations**

I=mr^2

ω=v/r

v=ωr

L=Iω

**3. The attempt at a solution**

L=Iω

I=mr^2

so L=(0.6)(.9^2)(ω)

ω=angular velocity is 3 rad/s

so L=(.6)(.9^2)(3rad/s)= Wrong answer
