U=0
T=20s
S=400m
$s = ut + \frac{1}{2} a {t}^{2}$

So 400=0+1/2a x 20 x 20
A=400/200=2

F = ma
1 tonne =1000kg
7 tonne = 7000kg
F= 7000 x 2
F=14000N

Hope this helps!!!

Ritankar2000: Then I have applied force=mass × acceleration

Ritankar2000: so mass is given as 7 ton i.e 7000 kg and acceleration is calculated in the first part of the problem.....so now applying values in f=ma equation we can get value of force

Ritankar2000: And value is 14000 kg ms^(-1) or 14000 N

Ritankar2000: hope this will help you

Ritankar2000: but paper pe kaise batau??

tanishka7856: please ease mat karo
