solve for a.

Now, you can use a to figure time up...

vf^2=2ad solve for vf, then vavg=vf/2, and time up=50/Vavg

However, in the real world, elevators do no have constant acceleration as they travel. The accelerate to a fixed set max velocity, then travel at that velocity. Think of the difficulty of a constantly accelerating elevator...such as stopping it at floor 100...
