Question

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.

Answer 1

Work is said to be done when an object moves due to a force applied. Work is calculated by multiplying the force applied and the distance traveled due to the force. It is expressed as:

W = Force x distance

W = 84 J = F (7.0 m)
F = 12 N

Hope this answers the question.

Answer 2

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.
