Two masses are connected by a rope which runs over a pulley, as shown below. The blue block has mass M and the red block has mass m. The blue block is heavier, M < m. Please look at the picture attached Part 1) Define up as the positive direction for both blocks. am is the acceleration of the red block and aM is the acceleration of the blue block, and both ropes have the same magnitude tension T. Which of the following mathematical statement is true? Select all that apply please A. Mg - T = M aM B. T - Mg = M aM C. T - mg = mam D. mg - T = -mam
