Homework Statement
I need to determine the total kinetic energy of a long thin rod relative to a laboratory frame which rotates around an axis at an angular velocity w and the axis moves at a constant translational velocity. The mass of the rod is M and the length of the rod is L. The translational velocity of the axis is Vaxis.
Homework Equations
Moment of Inertia, I, of rod is: 1/3 M (L sq) (This is because the rod rotates at one end).
The Attempt at a Solution
I believe the total kinetic energy should be: Total KE = 1/2 M (Vaxis sq) + 1/2 I (w sq).
Is this correct?
