i have two problems here where i have to find individual forces.

problem 1: i can't find the normal force. how would i do it?

Code (Text):
i tried 2123.328N *(2825.008-701.68) and also tried 701.68N but neither of them worked.

problem 2: i can't find the tension force

Code (Text):
i tried 32.438N and 132.948 *(165.386-32.438) but also neither of them worked.

Problem 1.
The normal force must produce the required centripetal acceleration.
This is also the case with problem 3.

Problem 1: Remember that in Newton's 2nd law, Fnet is a vector sum that reduces to (in this problem):
Fnet = Fnorm-Fgrav
Plug in your values appropriately to solve for the normal force on the pilot.

Problem 2: Same exact idea. You need to consider the directions of each force in order to add them together.
