While rearranging a dorm room, a student does 286 J of work in moving a desk 1.3 m. What was the magnitude of the applied horizontal force?

Work = force x distance

286J = Force x 1.3 meters

To find the magnitude of the applied horizontal force, we can use the formula for work:

Work = Force × Distance

Given that the work done is 286 J and the distance covered is 1.3 m, we can rearrange the formula to solve for force:

Force = Work / Distance

Substituting the given values:

Force = 286 J / 1.3 m

Calculating this value:

Force = 220 N

Therefore, the magnitude of the applied horizontal force is 220 N.
