2) A block sits on an inclined plane, which is slowlybeing raised. The block remains motionless until the angle theplane makes with the horizontal is 26°. At this angle, theblock begins to slide down the plane. What is the coefficient ofstatic friction between the plane and the block?
3) You and your friend are sledding on two sides of atriangle-shaped hill. On your side, the hill slopes up at 30.0°from the horizontal; on your friend's side, it slopes down at thesame angle. You do not want to climb up the hill, so you tell yourfriend to thread a rope through an ideal pulley that isconveniently atop the hill. He connects the rope to his sled andtosses the other end of the rope to you. The sleds on the snow havea coefficient of kinetic friction, k, of 0.0500. The totalmass of your friend and his sled is 82.0 kg while you and your sledhave a mass of 68.0 kg. (a) What is the magnitude of theacceleration of each sled? (b) What is the tension in therope?
