An object is dropped from a height of 49 meters. The object takes 3.2s to hit the ground. The final velocity of the object when it hits the ground is 31 m/s

Vo = 0 = Initial velocity.
V = 31 m/s. = Final velocity.
T = 3.2 s.
d = 49 m.
g = 9.8 m/s^2.
Everything is given. So what is the unknown or question?
