Alfonso pushes a box on a well waxed (frictionless) floor to the right with a 20 n force causing it to accelerate at 1.5 m/s2 . what is the mass of the box?

Many machines- including inclined planes such as ramps- increase the strength of the force put into the machine but decrease the distance over which the force is applied.
