1. The problem statement, all variables and given/known data
A man pushing a mop across a floor causes the mop to undergo two displacements. The first has a magnitude of 150 cm and makes an angle of 120 degrees with the positive x axis. The resultant displacement has a magnitude of 140 cm and is directed at an angle of 35 degrees to the positive x axis. Find the magnitude and direction of the second displacement (second vector)
2. Relevant equations
Vector Component Addition
3. The attempt at a solution
I realize that somehow, we know the resultant vector and one of the vectors and need to solve for the second vector. Because nothing is known about the second vector, I don't know how to go about that. I've been working on this problem all day and truly need some help.
