Answer 1

hope it helps you sis #niralii

thanks for so many thanks guys

love u all

Answer 2

Answer:

a = 2 m/s^2

F = 14000 N

Step-by-step explanation:

s = 400 m

t = 20 s

u = 0

mass = 7 metric tonnes = 7000 kg

s = 1/2 at^2

400 = 1/2 × a × 400

a = 2 m/s^2

Force = ma

= 7000 × 2

= 14000 N

Force = 14000 N
