Question

What is ​11918​ as a mixed number in simplest form?

Enter your answer in the box.

Answer 1

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
