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.
We need to use the concept of potential energy to solve this problem.
At the beginning, from a height ...
The solution looks at height and mass properties in relation to each other, using speed parameters to determine the specific height of the platform that the performer's assistance is deposited on.
