2. John pulls a 60 pound box along a level surface from left to right by attaching a piece of rope to the box and pulling on it with a force, F1, of 35 pounds in the direction 32° above the horizontal. A friction force, F2, of 8 pounds is acting on the box as it is being pulled. (A friction force acts in the direction opposite to the direction of motion.) a) Find the x and y components of F1. b) Find the x and y components of F2. c) Find the x and y components of F+F. d) Find the magnitude and direction of the net force acting on the box.
