Answer:
Given data:
Mass of stone(m)=7000 kg
Distance(S)=400 meter
Time(t)=20 second
1) We have to find the acceleration of the truck
So from the equation of motion S=ut+
2
1
a×t
2
, whereu=0
S=
2
1
a×t
2
a=
t

2×S
=
20×20
2×400
=2

m
2) Force acting on truck
So,from newton's 2
nd
law of motion
F
=ma=7000×2=14000N=14
