A jet travelling at a constant speed of `1.20 xx 10^(2)` m/s executes a vertical loop with a radius of `5.00 xx 10^(5)` m.(See fig.) Find the magnitude of the force (in N) of the seat on a 70.0 kg pilot at the top of the loop. (Take: `g=10 m//s^(2`)

Answer

A, C

Explanation

`N + mg = (mv^(2))/R`
`N + 700 =(70 xx (120)^(2))/(500)`
N=1316
