This question refers to the situation in Figure 2, above. The mass of block A is 3.3 kg. The mass of cart B is 5.7 kg. The mass of cart C is 8.4 kg. The plane under block B is inclined at an angle theta = 0 = 72 degrees away from vertical. The plane under cart C is inclined at an angle phi = p = 32 away from vertical. The coefficient of kinetic friction between block B and the plane beneath it is 0.41. The blocks are all moving. The velocity of Block A points downward, and none of the strings stretch. Assume the only significant forces in this situation are tension forces, normal forces, friction only between block B and the plane beneath it, and gravity with g = 9.81 m/s?. Calculate the acceleration of block A, in units of meters per second squared. The sign, positive or negative, of your answer is important and for this problem a positive acceleration points downward for block
