Hi!
Let's see how to proceed step by step. The first part (A) tells you to draw the free body diagram of the situation. This means that you need to draw each force applied to the seat and the girl. Since the combined mass of 50 kg is moving in circles around the pole, the force involved is centripetal.
The tension force acts from the seat to the pole. Now, you can use the information from part B to calculate the centripetal acceleration.

With this acceleration, you can then calculate the forces involved. I hope this helps, and if you have any other questions, feel free to ask!
Have a nice evening!
