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 θ and measure the speed at the lowest point in its swing to be vmax.
If we replace the wrecking ball with one of mass 2M, keeping the length of the chain and the angle θ at which the ball is released constant, how will vmax be affected?
