Answer:

The work done is [tex]32.2kJ[/tex]

Explanation:

Work is defined as the product of force and distance moved in the direction of application of force.

[tex]W= F*S[/tex]

Given Data

distance S= 230m

force F= 140 N

Mass of car m= 1140 kg

Applying the formula for work done we have

[tex]W= 140*230\\W= 32200 J\\W= 32.2kJ[/tex]

The work done by pushing the car for a distance of [tex]230m[/tex] is [tex]32.2kJ[/tex]
