If 84 J of work are exerted to pull a wagon, how much force does it take to pull the wagon 7.0 m? Round your answer to the nearest whole number.

It takes ______ N of force to pull the wagon.

Verified Answer :

By definition, the work done is given by:

\(W = Fd\)

Where,

F: force applied in the direction of displacement

d: distance traveled

Substituting values we have:

\(84 = F (7)\)

From here, we clear the value of force.

We have then:

\(F = \frac{84}{7}\)

Rewriting we have:

\(F = 12\)

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.
