## Homework Statement

a long, thin rod of mass M and length L is standing stright up on a table. its lower end rotates on a frictionless pivot. a very slight push causes the rod to fall over. as it hits the table, what are (a) the angular velocity and (b) the speed of the tip of the rod?

## Homework Equations

## The Attempt at a Solution

could we set up a conservation of energy equation for this?

1/2I(for spinning of rod)[tex]\omega[/tex]^2 + mgh = 1/2 I(for spinning of rod)[tex]\omega[/tex]^2 + 1/2I(for dropping of rod)[tex]\omega[/tex]^2
