SUMMARY
The acceleration of the block on the left in a pulley system involving two masses, M and m, is derived using Newton's second law, F=ma. The correct formula for acceleration is a = mg / (m + 2M), which accounts for the tension in the string. The initial attempt incorrectly simplified the equation, neglecting the effect of tension on the system. The final equations used to derive the acceleration are (M + m)g - T = (M + m)a and T - mg = ma.
