4) A pulley system consisting of 2 blocks A and B is shown in the figure. At time t=0 Block A is sliding down the inclined plane with a speed of Vo= 0.5 m/s and its position is x=0 metres. The coefficient of friction between block A and the inclined plane varies as a function of its position along the plane and is given as (-0.3-0.1x). The mass of block A is ma-8 kg and block B is me-4kg. The weight of the pulleys can be neglegted. The direction of the gravitational acceleration is shown in the figure and can be taken as g-9.81 m/s. Find the speed of the blocks after block A moves a distance of 2 m using work-energy equations.
