The center of gravity of the 3000-lb car is at G. The car is parked on an incline with the parking brake engaged, which locks the rear wheels. Find (a) the normal forces (perpendicular to the incline) acting under the front and rear pairs of wheels; and (b) the friction force (parallel to the incline) under the rear pair of wheels.

A father pulls his child on a sled by pulling on a rope over his shoulder with a forceas 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 weightof the sled and the child is about 180 N. Illustrate the concurrent forces on aCartesian plane and compute for the resultant force (magnitude and direction) on thesled.
