The diagram below is a top-down view of two children pulling a 13.1-kg sled along the snow. The first child exerts a force of F,I = 14.0 N at an angle 0, = 45.0° counterclockwise from the positive x direction. The second child exerts a force of |F, - 6.00 N at an angle 0, = 30.0° clockwise from the positive x direction. We use a right-handed coordinate system with the +x axis and +z axis in the horizontal plane, and the +y axis out of the page. 02
