Question

The magnitude and direction of two forces acting on an object are 110 pounds, S66E and 90 pounds, N68E, respectively. Find the magnitude, to the nearest hundredth of a pound, and the direction angle, to the nearest tenth of a degree, of the resultant force.

Answer 1

We know the resultant force will have components of its own, so resolve these two vectors to components and sum them up component by component.
