What force was applied to an object if 35 J of work was done and the object moved 7 m? Show your work.

ahrayia [7]

Answer:

5 N

Explanation:

The work done by a force on an object is (assuming that the direction of the force is parallel to the displacement of the object):

$W=Fd$

where

F is the magnitude of the force

d is the displacement of the object

In this problem, we know that:

W = 35 J is the work done

d = 7 m is the displacement of the object

Therefore, we can re-arrange the equation to calculate the force applied:

$F=\frac{W}{d}=\frac{35 J}{7 m}=5 N$
