I believe the answer is A true
Answer:
= 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
