Solve the all parts of given problem:

Problem: A 25kg child swings on a playground swing. If the swing hands down 2m from the top bar, and the child swings out 10 degrees,

Part A: What is the height above ground of the child at this angle?

Part B: What is the change in potential energy of the child?

I need help to solve the above problem and the swing is initially 0.75m off the ground.
