c) A block (mass ma) lying on a fixed frictionless inclined plane is connected to a mass me by a cord of negligible mass passing over a pulley, as shown. i. ii. Determine a formula for the acceleration of the system in terms of mA, MB, , and g. What value of m, in terms of mA, O, and g, would keep the system at rest? What ratio, mA/MB would allow the masses to move at constant speed along their ramps in either direction? MB MA 0
