Calculating Work: 15.0N Object Moved 3.00m with a 60.0N Force

[blue__boy]

A 15.0N object is moved horizontally 3.00m across a level floor using a horizontal force of 60.0N. how much work is done on this object?

I am not sure should I use 15.0N or 60.0N to find the work

Thanks for helping!

I think you'd use 60.0 N.
15.0N is just the mass in kg times gravity.

Remember forces that are perpendicular to the direction of motion do no work. Here the 15N Weight is perpendicular to the direction of motion, whereas the 60N force is parallel to the direction of motion.
