Jet fighter flying in a vertical loop

[jstretto]

Homework Statement

A jet fighter flies in a vertical circle of diameter 1000 m. The speed of the aeroplane at the bottom of this circle is 185 m s-1. For the aeroplane at this point, calculate:
Apparent weight

Homework Equations

Fc = mv^2/r
Ac = v^2/r
Fn = Fg + Fc

The Attempt at a Solution

I cannot find a single way to find the apparent weight of something without mass, it is doing my head in. I have scowered the internet and nothing. Please help me!

What if you were to let M be the mass of the aircraft? What would you get? Can you work out the acceleration components?

 

[FactChecker]

I agree with you. Unless you are given the mass, you can not calculate the "apparent weight". However, you can calculate the number of g's and you can calculate a multiplying factor, A, of whatever the weight is: apparentWeight= A*airplaneMass.

@jstretto : This problem does have a solution . You would find it much easier to understand the problem and get to the solution if you drew a simple diagram .
