Figure shows a block (mass m1) on a smooth horizontal surface, connected by a thin cord that passes over a pulley to a second block (m2), which hangs vertically.
1. Obtain formula for the acceleration of the system and tension in the cord.
2. If m1 and m2 interchanges its position, will it affect the tension of the string?
3. What is the acceleration of the system if m1 = 5 kg and m2 = 2kg?
