A truck falls off a cliff. If the cliff is 33.5 m high, how much time for the truck to reach the bottom?

Displacement = -33.5m

Acceleration = 9.8 m/s^2

t = ?

I can't use any of my equations because I need at least 2 known variables

should I make the acceleration a negative number because I keep getting a negative number that doesn't make sense?
