2. Two blocks initially at rest, each having a mass of 20 kg, are connected by a string as shown in the figure. The coefficient of sliding friction between the block and the inclined plane is 0.28. The plane is inclined at 350 with the horizontal. The blocks are accelerating at a magnitude of 0.8 m/s2. Assuming the pulleys to be light and frictionless. If the work due to force of friction at B is -105.84 J, find: a. The displacement moved by the block. ( Ans. -3.0 m) b. The work done by the Normal force at B. (Ans. O J) c.
