10. Four forces act on a hot-air balloon, shown from the side in the figure below. Find the magnitude and direction of the resultant force on the balloon. 5120 N 1520 N 950 N 4050 N 11. Two lifeguards pull on ropes attached to a raft. If they pull in the same direction, the raft experiences a net force of 334 N to the right. If they pull in opposite directions, the raft experiences a net force of 106 N to the left. a. Draw a free-body diagram representing the raft for each situation. b. Find the force exerted by each lifeguard on the raft for each situation. (Disregard any other forces acting on the raft.) 12. A dog pulls on a pillow with a force of 5 N at an angle of 37" above the horizontal. Find the x- and y-components of this force
