Two forces, with magnitudes 5.0N and 12N, act from the same point on an object. Calculate the magnitude of the resultant force R for the forces acting An object X rests on a smooth horizontal surface. Two horizontal forces act on X as shown in [Figure 1.1]. A force of 55N is applied to the right. A force of 18N is applied at an angle of 115° to the direction of the 55N force.
