Question

An object is acted upon by two forces 100N and 80N. Calculate the resultant of two axis, if they are acting at angle of 120° too each other.​

Answer 1

Below

Step-by-step explanation:

Here is one possibility:

Vertical components added together = 80 sin 120 + 0 = 69.28

Horizontal components = 80 cos 12 0 + 100 = 60 N

Resultant magnitude = sqrt ( 69.28^2 + 60^2) = 91.65 N

Angle = arctan (69.28/60)=49.1°
