4. For this series of 4 questions, two blocks, A and B, are connected using the cable and pulley system as shown. (The cable and pulley system is friction-less and weight- less.) The coefficient of kinetic friction between block A and the inclined plane is μ = 0. 2. Initially the blocks are moving but eventually come to stop. You will be asked to solve for different things. Please pay attention: the numbers may change from problem to problem since they are randomized. 4) If block A weighs 100 lb and block B weighs 65 lb, and initially block A moves down the plane at a velocity of 7.1 ft/s, determine how far block A will move along the surface until it stops. Your answer must include 2 places after the decimal point and the proper unit. Take g = 32.2 ft/s². A Your Answer: Answer B units C D
