Mechanics help :(!
I REALLY NEED HELP :(
Two blocks are connected by a cord which passes over a frictionless pulley at D.
Block A has a mass of 40 kg and block B a
mass of 120 kg. A rests on a horizontal
surface, while B rests on a ramp with the slope
shown. B is initially in a position 3 m from the
stop C as shown. The coefficient of kinetic
friction between the blocks and the surface
beneath is μK = 0.20 for both A and B.
(a) Find the acceleration of the two blocks and
the tension T in the cord, assuming that the
blocks just begin to move at time t = 0.
