# Wrecking ball

A wrecking ball is a heavy metal mass that's swung, from a crane, into structures to demolish them. Suppose we release a ball of mass $$M$$ from initial angle $$\theta$$ and measure the speed at the lowest point in its swing to be $$v_\textrm{max}.$$

If we replace the wrecking ball with one of mass $$2M,$$ keeping the length of the chain and the angle $$\theta$$ at which the ball is released constant, how will $$v_\textrm{max}$$ be affected?


Details and Assumptions:

• Neglect air resistance.
• The mass of the chain is zero.
