A father pulls his child on a sled by pulling on a rope over his shoulder with a force as much as 75 N directed along the rope that makes an angle of 30 0 with the ground. The icy ground exerts about 15 N frictional force on the sled. The combined weight of the sled and the child is about 180 N. Illustrate the concurrent forces on a Cartesian plane and compute for the resultant force (magnitude and direction) on the sled.
