Question

This is a depiction of 2 forces acting on a puck (top view). Which direction would a 3rd force have to be to balance the forces? DIAGRAM BELOW

Answer 1

Assuming that Force1(F1) is has 90 degrees upward and assuming that Force2(F2) has 0degrees,

Answer 2

First you do vector addition. F1 + F2 = F3 (should come out with magnitude and direction or degrees)

Answer 3

Lastly, the 3rd force(F4) to make the puck be at equilibrium is 180 degrees away from F3. F4 = F3 + straight opposite direction of F3
