Calculating Jet Speed in Vertical Loop: Centripetal Force Question 1 Explained

[TheExibo]

1. A jet pilot feels 5.00 times her normal weight at the bottom of a vertical loop. The loop has a radius of 1.50 km. What is the speed of the jet at the bottom of the loop?2. F(centripetal)=(mv^2)/r3. The problem I'm having is with this equation that I've made based on the equation: F(c)=F(n)-F(g). With it, I get the answer of 242m/s (mass is not necessary to solve the question). Would (v^2)/1500=(9.8*5)-(9.8) be the correct step to solving this problem? Thanks!

Yes. It is correct.
