By definition, the work done is given by:

[tex] W = Fd [/tex]

Where,

F: force applied in the direction of displacement

d: distance traveled

Substituting values we have:

[tex] 84 = F (7) [/tex]

From here, we clear the value of force.

We have then:

[tex] F = \frac{84}{7} [/tex]

Rewriting we have:

[tex] F = 12 [/tex]

Answer:

It takes 12 N of force to pull the wagon.

The force required to pull a wagon if 84 J of work are exerted to pull a wagon 7m is 12 Joules.

HOW TO CALCULATE WORK DONE:

  • Work done can be calculated by multiplying the force applied on an object by the distance traveled. That is;

Work done = Force × distance

Force = Work done ÷ distance

  • According to this question, the work done is 84J and the wagon was pulled to a distance of 7 metres. The force is calculated as follows:

Force = 84J ÷ 7m

Force = 12N.

Therefore, the force required to pull a wagon if 84 J of work are exerted to pull a wagon 7m is 12 Joules.
