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 MM from initial angle θ\theta and measure the speed at the lowest point in its swing to be vmax.v_\textrm{max}.

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


Details and Assumptions:

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