Three forces acting on a spherical mass M are depicted in the diagram below. 60 50 Submit Answer Tries 0/12 Force, Vertical-component (N) 40 30 20 10 0 -10 -20 -30 -30-20-10 0 10 20 30 40 50 60 70 80 Force, Horizontal-component (N) A. Calculate the magnitude and direction (i.e., the angle with respect to the positive H-axis, measured positive as counter-clockwise) of the total force acting on M. Notice that the arrows representing the forces end on grid intersections. Magnitude: Direction: B. When a fourth force is applied to the mass, it is observed that the velocity of the mass stops changing and remains constant. What are the horizontal and vertical components of that fourth force? Horizontal: Submit Answer Tries 0/12 Vertical:
