I am having a lot of trouble with this problem. Can anyone help me?(adsbygoogle = window.adsbygoogle || []).push({});

A 20.0 kg sphere of soft lead is suspended from the tip of a pole by a 1.5 m wire such that it is free to swing in a complete verticle circle. Someone takes a crossbow and fires a steel bolt horizontally, mass of 0.50kg, such that it imbeds itself in the soft lead. What was the speed needed by the sphere to perform a complete vertical loop? b) What was the speed initial of the bolt be before the collision?
