Can anyone solve this question ⬆​

Answer 1

Answer:

Ans.14000N mark me as brainlist

Step-by-step explanation:

Initial velocity, u = 0

Distance travelled, s = 400 m

Time taken, t = 20 s

We know, s = ut + ½ at2

Or, 400 = 0 + ½ a (20)2

Or, a = 2 ms€“2

Now, m = 7 MT = 7000 kg, a = 2 ms€“2

Or, F = ma = 7000 — 2 = 14000 N Ans.
