How Does Table Height Affect Initial Velocity Calculation in Physics?

[FireSystems]

Homework Statement

I am trying to calculate the (Vo) for a ramp length from a horizontal decline marked at
20 cm. The ramp on top of a table has an angle of 41 degrees. I performed 3 trials releasing a ball bearing at the 20cm mark and averaged 53.3 . The table height is 87.3 cm. Isn't Vo 0?

How do I find the Initial Velocity of the ramp length?

Homework Equations

Given equations on Lab sheet Vo=ΔX/t

The Attempt at a Solution

All I did was 53.3/9.8m/s. I am really new at this, any help would be appreciated.

Explain a bit more completely what you're doing and what you're to find out.

What does the height of the table have to do with anything?
