I used a calculator
Answer:
266.0 s ≈ 4.4 min
Step-by-step explanation
1) Data
Wr = 43,576 N
F = 11,918 N
V = 713 m/s
t =?
2) Principles and formulas
Impulse and conservation of momentum
I = F.t = Δp
Δp = mΔv
3) Solution
m = Wr / g = 43,576N / 9.8 m/s^2 = 4,446.5 kg
Δp = mΔv => 4,446.5 kg * 713 m/s = 3,170,354,5 N*s
I = F.t = Δp => t = Δp / F = 3,710,354.5 N*s / 11,918N = 266.0 s
t = 266.0 s ≈ 4.4 min
