= 746.58N

Explanation:

where,

"m" is the mass of the body

"v" is the linear velocity of the body

"R" is the radius of the circular path.

Mass of the pilot is m = 150 lbs = 68.0389kg

Speed of the pilot is v = 120 ft/s. = 36.576m/s

The radius of the loop is R = 400 ft = 121.92m

F = mv²/R

= (68.0389 * (36.576²)) / 121.92

= 746.58N
