## Homework Statement

Two heavy balls of equal mass M are attached to the long but light metallic rod standing

on the floor. The rod with the balls falls to the floor. Find the velocity of each ball at the moment

when the rod hits the ground. Neglect mass of the rod and the friction between the balls and the

floor.

## Homework Equations

E1=Ef

m1v1 + m2v2 = m1v1 + m2v2

E1 = mgh

## The Attempt at a Solution

Mass 2 initial energy = mgh, mass 1(on floor) = 0

When rod falls Mass 2 = 0; mass 1 = 0.5mv^2

so mgh = 0.5mv^2

V=sqrt(2gh) ??
