what is the net force of a 15.0-N force and a 28.0-N force act in the same direction

Question

what is the net force of a 15.0-N force and a 28.0-N force acting on an object if these force

act in the same direction

Answer 1

Force is a vector, so the direction matters when adding vector quantities.

If both forces are in the same direction, the net force will be:

Fnet = F1 + F2 = 15 N + 28 N = 43 N

and it will point in the same direction as the two forces.
