Work (W) is measured in joules using the formula W = f · d where f is the force in newtons and d is the distance over which the force is applied in meters.

If 36 joules of work are needed to move a box a distance of 9 meters, how much force was applied to the box?

Respuesta :

Force is 4 joules per meter, which is equal to 4 newtons, because 1 joule per meter=1 newton
