Homework Statement



A 1000 kg elevator is held up by two cables. If each able exerts a force of 6000N upwards upon the elevator, find the elevator's acceleration.


Homework Equations



Fg=mg

FNET=ma


The Attempt at a Solution



I started with a force diagram to help me and then I think I'm supposed to use the FNET=ma formula. So I plugged in the variables as follows: (6000+6000)-Fge=1000a
How do you solve for acceleration in this problem when I also need to find the Force that gravity exerts on the elevator (Fge)?

Would the answer be 2.2m/s^2?

Fge would simply be the weight, mg, of the elevator.
