Problem 3: While sliding a couch across a floor, Hannah and Andrea exert forces FH and FA on the couch. Hannah's force is due north with a magnitude of FĦ = 115 N and Andrea's force is 0 = 32° east of north with a magnitude of FA = 217 N. In this problem, use a coordinate system with positive y directed north and positive x directed east.

Newton's Second Law

Newton’s laws of motion describe the relationship between the motion of an object and forces acting on it. Newton’s law of motion has two types as follows:
