Question

200 J of work is done when a force is applied to an object and the object moves 10 m to the right. How much Force was applied?

Answer 1

20N

Step-by-step explanation:

Given parameters:

Work done = 200J

Distance moved = 10m

Unknown:

Amount of force applied =?

Solution:

Work done is the force applied on a body to move it in the direction of the force.

Work done = force x distance

The unit of work done is in joules

Since the unknown is force, we make it the subject of the expression;

Force =
`(Work done)/(distance)`

Force =
`(200)/(10)` = 20N
