Question

a cart with mass 30 kg went 40 m in a straight line on a plain and smooth road when a force of 3N was applied to it. how much work was done by the force

Answer 1

Given:
Force=F=3N
Displacement =s=40m
Workdone=?

Formula to be used
Workdone=Force x displacement
=3 x40
=120 joules

Therefore work done is 120J

Answer 2

Hey!
Given,
Mass(m) = 30 kg
Displacement(s) = 40 m
Force(f) = 3 N

We know,
Work done = force x displacement
                   = 3 x 40
                   = 120 J
