A meter stick is held vertically with one end on the floor and is then allowed to fall. Find the speed of the other end when it hits the floor, assuming that the end on the floor does not slip. (Hint: Consider the stick to be a thin rod and use the conservation of energy principle.)

your initial PE turns to final PE and final rotational KE, right?

initial PE= mg(h/2)
final PE= mg(0)
rotational KE= 1/2 I w^2=1/2 I v^2/r^2
