It depends on the direction of the two forces. If the two forces are in the same direction, the net force would be 60N or -60N. If the two forces are in opposite directions the net force would be either 30N or -30N.
net force=75-30=45N
The child dragged his toy truck across the room, leaving a trail of marks on the floor.
The past of "to drag" is "dragged." For example, "She dragged the heavy box across the floor."
Friction will stop it.

kinetic friction
the paper slows down due to gravity, and friction, there are small hills and valleys that are not seen.
Static friction
Because of the forces that act on the ball in the direction opposite to its motion ... air resistance and friction with the floor.

Because of the friction in the carpet fibers.
