Homework Statement
A sphere with mass 0.4 kg circles around a circular trajectory with ray 2 m and angular speed 12 rad/S. Which is the momentum of the impulse of the sphere?
Homework Equations
L=Iw=2/5mr^2w
w(angular speed)
or
L=mr^2w
The Attempt at a Solution
I think we should use the first formula becuase the I (inercy momentum) of sphere, but in the solution it is used L=mr^2w. Which is correct?
