A 25-kg box is attached to two-light ropes and is being pulled in a frictionless, horizontal floor. The two forces pulling box is given: F1 is 15 N due to east, and F2 is 10 N due north. a) Draw the free-body diagram b) What are the forces acting on the box? Identify whether contact or non-contact force. c) Identify the action-reaction pairs d) What is the acceleration of the box?
