An elevator contains two masses: M1 = 2.0 kg is attached by a string (string 1) to the ceiling of the elevator, and M2 = 4.0 kg is attached by a similar string (string 2) to the bottom of mass 1.

Find the tension in string 1 (T1) if the elevator is moving upward at a constant velocity of v = 3.0 m/s.

Find T1 if the elevator is accelerating upward with an acceleration of a = 3.0 m/s2

What is the tension in string 2 (T2) if string 1 suddenly breaks?
