(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A ball rolls off an incline plane on top of a 1m high table and strikes the floor 62.5cm from the edge of the table. What was the velocity of the ball just as it left the incline plane?

The incline is given as 30 degrees.

I've put my frame of reference at the point where the ball is at the edge of the table about to fall off.

2. Relevant equations

1. Position final = Position initial + (Velocity initial * time) + (1/2 Acceleration * time^2)

2. Velocity final = Velocity initial + (Acceleration * time)

3. The attempt at a solution

Since my frame of reference is placed where it is, in the x direction the acceleration is 0 as well as the initial position. So formula 1 in the x-direction boils down to:

.625m = (Velocity initial * time)

Or in other words:

Vi = .625/t

I tried to solve for t in the y-direction but that's where I got stuck. It travels down the ramp first so its initial velocity and position as well as the final velocity are unknown.

Stuck. Thanks for any and all help.
