Compute each part of given question:
Question: Two objects (49.0 and 15.0 kg) are connected by a mass less string that passes over a mass less, frictionless pulley. The pulley hangs from the ceiling.
Part A: Find the acceleration of the objects?
Part B: Find the tension in the string?
Please explain how you came to your conclusion.
