Question

A 405-N rightward force is used to drag a large box across the floor with a constant velocity of 0.678m/s. The coefficient of friction between the box and the floor is 0.795. Determine the mass of the box.

Answer 1

In balanced forces, the two individual forces act in opposite direction. Conversely, in unbalanced forces, the individual forces either act in same or opposite direction. A non-contact force is a force which acts on an object without coming physically in contact with it.
