Given that
Fnet = F1 + F2 + F3 + F4 = 4.0 i N
Fnet = (4.0 i + 0 j) N
from given diagram
F1x = 0 i N
F1y = -5 j N
F2x = 6*cos 20 deg = 5.64 i N
F2y = 6*sin 20 deg = 2.05 j N
F3x = 0 i N
F3y = F3y j N
F4x = F4x i N
F4y = 0 j N
Now Add all of them
F1 + F2 + F3 + F4 = (0 i - 5 j) + (5.64 i + 2.05 j) + (0 i + F3y j) + (F4x i + 0 j)
= (0 + 5.64 + 0 + F4x) i + (-5 + 2.05 + F3y + 0) j
= (5.64 + F4x) i + (F3y - 2.95) j
Given that Fnet = (4 i + 0 j ) N
Compare both equations
(5.64 + F4x) i + (F3y - 2.95) j = 4 i + 0 j
5.64 + F4x = 4
F4x = 4 - 5.64 = -1.64 N
F3y - 2.95 = 0
F3y = 2.95
Final answer
F3x, F3y = 0, 2.95
F4x, F4y = -1.64, 0
You have to enter two values in answer separated by commas.
