Consider the mass and pulley system shown. Mass m1 = 33kg and mass m2 = 13kg . The angle of the inclined plane is given, and the coefficient of kinetic friction between mass m2 and the inclined plane is μk=0.19. Assume the pulleys are mass less and friction less. What is the acceleration of mass m2 on the inclined plane? Take positive acceleration to be up the ramp. If the system is released from rest, what is the speed of mass m2 after 3.5s ?When mass m2 moves a distance 3.52m up the ramp, how far downward does mass m1 move?
