Homework Statement



A stick of mass M, length L is standing upright on a table, pivoted at the bottom.
What is its angular velocity as it hits the table?



Homework Equations



ang. accel = (3g/2L)cos theta (theta is zero with stick laying on table)



The Attempt at a Solution



ang. vel = integral of ang. accel wrt to time, theta is some function of time.
Elliptic integral?

Numeric solution??

Thanks.
