What is the initial velocity of an object that rolls off a table and hits the floor below?

Lab produced the following data:

Table height: 86 cm

Distance of object from table when it hits floor: 23 cm

Relevant equations

Instantaneous Speed: Vf = Vo + at

[I think this is the correct one...]

The attempt at a solution

Gravity affects the object at a rate of 9.8 m/s.

Converting dimensions to meters:

86 cm = .86 m

23 cm = .23 m

I know gravity affects the height and the velocity affects the distance from the table and these two do not affect each other, but how do I determine the time?

You can't use sin and that triangle stuff because the object arches, it isn't straight.

I'd applicate any help or hints you could provide to help me threw this problem.
