Exercise 98

A 1.5-kg object moves up the y -axis at a constant speed. When it reaches the origin, the forces F 1 = 5.0 N at 37° above the + x -axis, F 2 = 2.5 N in the -Ex-direction, F 3 = 3.5 N at 45° below the x -axis, and F 4 = 1.5 N in the y -direction are applied to it. (a) Will the object continue to move along the y -axis (b) If not, what simultaneously applied force will keep it moving along the y -axis at a constant speed
