This is a fairly simple Question but I just can't figure it out. If there is an object and there are two forces that act on the 5 kg object (say this object is located on the origin of an sy plane) and F1= 25 N and points in the 0 degrees direction and the other force, F2= 15 N and points 60 degrees counterclockwise from the x axis/ F1, what would be the direction of the total force counterclockwise from the x axis??

Do you know how to do vector addition? If so, then this question is simple. You can, in fact, add up the x and y components separately:

x components:

(25 N) + (15 N)cos(60 deg)

y components

0 + (15 N)sin(60 deg)

So what angle does the resultant vector make with the x-axis?
