Homework Help: physics

Posted by Anonymous on Sunday, October 7, 2007 at 8:57pm.

The cavle on an elevator is what pulls the elevator up, and allows it to come down safely. The mass of the elevator is 1400 kg. If the elevator starts from rest and is pulled upwards with a constant tension of 18 kN, what will its speed be after moving 6m? (Assume no frictioanl force)

so i first drew a force diagram to find the total forces
Tension- Fgravity=ma
a= 12.85 m/s

so now that I have found the acceleration of the elevator I need to help finding the its speed after 6m..I'm not sure how I would start doing that
