An elevator of mass M2 has hanging from its ceiling (on a massless string) a mass M1. The elevator is being accelerated upward by a constant force F [F greater than (M1 + M2)g]. The mass M1 is initially a distance s above the elevator floor.
Find the acceleration of the elevator.
What is the tension in the string connecting the mass M1 to the elevator?
If the string suddenly breaks, what is the acceleration of the elevator immediately after? What is the acceleration of mass M1?
How long does it take for the mass M1 to hit the bottom of the elevator?
