Can anyone help me with this?(adsbygoogle = window.adsbygoogle || []).push({});

A steel wrecking ball of mass 200kg is fastned to a 10m long chain which is fixed at the far end to a crane. The ball is released when the chain is horizontal. At the bottom of the path the ball strikes a 1000kg car initally at rest on a frictionless surface. The collision is completely inelastic so that the ball and car move together just after the collision. What is the speed of the ball and car just after the collision.
