Force plane exert on pilot = 4270 N

Explanation:

first convert radius and speed to ms

using formula from force we know that

mass = weight / gravity = 700 N / 9.8N/kg = 71.4 kg

Fc = N-mg

N = Fc + mg As Fc = mv²/R

N = mv²/R + mg

taking m common

N = m (v²/R + g)

= 71.4 ((200) ² / 800 + 9.8)

Force = 4270 N
