If F1, stands for a force vector of magnitude 30.0 N and F2 stands for a force vector of magnitude 40.0 N
acting in the directions, what are the magnitude and direction of the resultant
obtained by the vector addition of these two vectors using the analytical method?

F2
60°
F1

Expert Solution
Step 1

The magnitude of resultant force vector of two force vectors F1 and F2 , is calculated using cosine law,

F = (F12 + F22 + 2F1F2 cosθ)1/2

θ is angle between
