The resultant is the sum of the two displacements having the same direction as the orig b. Which indicates that the resultant force R has the same direction as a, and has magnitude equal to the product m a.. For example, if a box of 1.5 kg is subject to 5 forces which make it accelerate 2.0 m/s 2 north-west, then the resultant force is directed north-west and has the magnitude equal to 1.5 kg × 2.0 m/s 2 = 3.0 N.. Often, however, we know the forces that act on an object and we need . Calculate the resultant force and the force that must be applied to the object to create equilibrium.
