Answer to Question #139251 in Physics for philip

Question

A body is under the action of two forces 8N and 9N. Find the resultant of the two forces if the force are parallel act in the same direction?

Answer 1

If the forces are parallel abd act in the same direction, then we need basically add their magnitudes. Thus, the resultant force will have the magnitude:

$$F_{res} = 8N+9N = 17N$$

and will be directed in the same direction as two initial forces.

Answer. 17 N, directed in the same direction.
