1. The problem statement, all variables and given/known data 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 2. Relevant equations Fc = mv^2/r Ac = v^2/r Fn = Fg + Fc 3. 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!
