1. (10) Two girls are trying to pull a toboggan out of a deep snow drift that provides an opposing force of 8.0 N. They are using ropes attached to the toboggan and parallel to the ground. The direction of the forces exerted by the girls are shown, from above, in this diagram. The girl that pulls the rope under the angle 20° is applying 16 N force, the second one is applying 11 N force with an angle of 30. Calculate the net force acting on the toboggan.
