A 1.5 kilogram object moves up the y-axis at a constant speed. When it reaches the origin, the forces F1=5.0 Newton at 37 degree above the + x-axis, F2=2.5 Newton in the +x-direction, F3=3.5 Newton at 45 degree below the-x-axis, and F4= 1.5 Newton in the -y-direction are applied to it.
(a) Determine will the object continue to move along the -y-axis?
(b) If not, find what simultaneously applied force will keep it moving along the y-axis at a constant speed?
