The work done by the man pushing the car over the given distance is 1000J.
Given the data in the question;
- Mass of car;
- Acceleration of the car;
- Distance covered by the car;
Work done;
Work done is simply defined as the energy transfer that takes place when an object is either pushed or pulled over a certain distance by an external force. It is expressed as;
Where f is force applied and d is distance travelled.
To determine the work done by the man, we first solve for the force applied F.
From Newton's Second Law;
We substitute our given values into the expression
Next we substitute our values into the expression of work done above.
Therefore, the work done by the man pushing the car over the given distance is 1000J.
