Three Forces are applied to a large boulder in an attempt to move it. The Forces are F1=(600N, 130 degrees), F2=(780N, 200 degrees), and F3=(550N, 165 degrees). What is the net force acting on the boulder? If the boulder does not move, what is the resistive force acting

2. Relevant equations

Vx= Vcos

Vy= Vsin

3. The attempt at a solution

Used Vx= Vcos and Vy= Vsin for each force and got

y: 450+(-267)+(142) = 325

x: (-386)+(-705)+(-531) = -1622

1622(-i) + 325 (j) for the resulatant or net force.

the second part of the question is what im stuck on. i guess from the resultant the boulder is moving so there has to be a resistive force but i don't know how to get there.
