Question

A motorist runs out of gas on a level road 230m from a gas station. The driver pushes the 1140kg car to the gas station. If a 140 N Force is required to keep the car moving, how much work (in J) does the driver do?

Answer 1

Answer:

The work done is $32.2kJ$

Explanation:

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

$W= F*S$

Given Data

distance S= 230m

force F= 140 N

Mass of car m= 1140 kg

Applying the formula for work done we have

$W= 140*230\\W= 32200 J\\W= 32.2kJ$

The work done by pushing the car for a distance of $230m$ is $32.2kJ$
