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

An autographed baseball rolls off of a 1.2 m high desk and strikes the floor 0.41 m away from the desk. The acceleration of gravity is 9.81 m/s2 . How fast was it rolling on the desk before it fell off?

Answer in units of m/s.

2. Relevant equations

You might need to use

v^2=vi^2 + 2a(x-xi)

although I'm not really sure. :/

3. The attempt at a solution

I'm not sure how to solve this when you're not given the velocity :( I just need someone to explain how to do this, because there's 3 problems on my homework exactly like it but with different numbers. Thank you~
