6. Forces with magnitudes of 120 newtons and 350 ба.
newtons act on an object. The angle between the
forces is 40°. Find a) the direction and b) the magnitude
6b.
of the resultant of the forces. (Hint: write force 1 as a vector in the direction of the positive x-axis and force 2
as a vector at an angle with the positive x-axis.)
