2. (20 pts) A 22 kg disk is sitting at rest on a ramp inclined from the horizontal by an angle 6 = 38. A parallel section of rope is holding the disk to a wall at the top of the ramp. What is (a) the tension in the rope and (b) the force of static friction between the disk and the incline? (c) What minimum coefcient of static friction must exist between the ramp and disk? ((1) If the rope suddenly breaks, how long will it take the disk to roll a distance of 50 cm Without slipping
