Hola...

Explanation:

Initial Velocity (u) = 0 m/s

Distance (s) = 400 m

Time (t) = 20 s

Mass (m) = 7000 kg

To find force we need to find acceleration.

We can find acceleration by the second law of motion,

s = ut + 1/2 at²

400 = 0 × 20 + 1/2 × a × (20)²

400 = 0 + 200a

a = 400/200

a = 2

Now, Force = Mass × Acceleration

F = 7000 × 2

Force = 14000

Hope This Helps You!!!

Have A Great Day Ahead!!!
