This question again refers to the situation in the inclined plane diagram above. Again, Carts B and C roll with negligible friction. The only significant forces in the problem are tension forces, normal forces, and gravity with g = 9.81 meters per second squared. The mass of block A is 2.6 kg. The mass of cart B is 2.4 kg. The mass of cart C is 1.6 kg. The angle theta = 0 = 63 degrees. Calculate the acceleration of block A in units of meters per second squared. Choose the positive direction for block A to be upward (an upward acceleration is positive and a downward acceleration is negative).
