An object of mass m has these three forces acting on it (there is no normal force, "no surface"). f1 = 1 n, f2 = 9 n, and f3 = 5 n. when answering the questions below, assume the x-direction is to the right, and the y-direction is straight upwards.

solved

Explanation:

a) F_net = (F2 - F3)i - F1 j

b) |Fnet| = sqrt( (F2 - F3)^2 + F1^2)

= sqrt( (9- 5)^2 + 1^2)

= 4.123 N

c) θ = tan^-1( (Fnet_y/Fnet_x)

= tan^-1( -1/(9-5) )

= -14.036°
