A father pulls his child on a sled by pulling on a rope over his shoulder with a force as much as 70 N directed along the rope that makes an angle of 30 degrees with the ground. The icy ground exerts about 20 N friction force on the sled. The combined weight of the sled and the child is 160 N. Compute the resultant force on the sled using the graphical method. Use scale factor: 1.0 cm : 10 N
