Block a has a mass 1.0 kg and block b has a mass 3.0 kg. the two blocks are connected by a very light rope of negligible mass that passes over a pulley as shown. the coefficient of kinetic friction for the blocks on the ramp is 0.33. the ramp is angled at  = 45. at time t = 0 s, block a is released with an initial speed of 6.0 m/s. what is the tension in the rope?
