Question

please give me answer friends ​

Answer 1

Answer: 700 newton

Explanation:

Answer 2

Explanation:

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+1/2 a×t^2

where u=0, we get

=2m/sec^2

2) Force acting on truck

So, from newton's 2nd law of motion

F =ma

=7000×2

=14000N

=14kN
