Explanation / Answer

3. (a) |F1| = sqrt((-2.62)^2 + (-5.31)^2)

F1 = 5.92 N  

direction = 180 + tan^-1(5.31 / 2.61) = 244 deg

(B) F2 = sqrt(3.45^2 + 1.87^2) = 3.92 N

direction = 180 - tan^-1(1.87 / 3.45) = 152 deg  

(C) F = F1 + F2 = - 6.07 N i - 3.44 N j

magnitude = 6.98 N

direction = 180 + tan^-1(3.44 / 6.07) = 210 deg
