Height and Speed on Trapeze

A circus perfomer swings down on a trapeze from a height of 18m (starting from base ground). He picks up an assistant standing on the floor, and just reaches a platform of height h, depositing the assistant on the platform as they reach zero speed together. The performer's mass is 100kg and his assistant's mass is 50kg. The length of the trapeze rope is 20m.
A) What is the height h of the platform that the assistant is deposited on? Please use the visual illustration attached to help you.
