<h3>What is sound wave?</h3>
A sound wave is the pattern of disruption brought on by the movement of energy moving through a medium as it propagates away from the source of the sound (such as air, water, or any other liquid or solid substance). Pressure waves are produced when an item vibrates, such as a ringing phone, and these waves are known as sound waves. The surrounding medium's particles are disturbed by the pressure wave, and those particles disrupt the particles next to them, and so on. Like ocean waves, the disturbance's pattern causes outward movement in all directions. Usually in all directions and with decreased intensity as it gets further away from the source, the wave transmits the sound energy through the medium.

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.
