A 21.1 kg child sits in a swing supported by two chains, each 1.85 m long. Assume the mass of the seat and chains is negligible. The tension in each chain at the lowest point is 194 N. Determine the maximum height (in m) as measured from the lowest point that the child will attain after swinging upwards.

I have no idea how to solve this, i tried asking for and looking for help online and there was apparently a similar question asked before but not asking for the same thing. the ai also keeps trying to calculate the wrong thing
