Okay, so what I (think) I've got here is:

Initial Velocity = 35 m/s

Acceleration = -20 m/s^2

D= ?

Final Velocity = 0 m/s

What I don't know is how to crunch it properly, and the acceleration being in m/s^2 compounds the problem.

I feel silly asking, but any help would be tremendously appreciated.
