Projectile Motion: Calculating Speed of Ball Thrown from Third Floor Window

[QUOTE="billy_joule, post: 5214383, member: 515386"] Correct: You know gravity will act in the Y direction which will cause a downward acceleration. What is the initial velocity in the Y direction? It isn't -25m/s as you've calculated, that would be true if the ball was thrown straight down but it isn't. it depends on the initial angle.. The equation you've used has time as the unknown, but are you interested in finding the time? You have an initial velocity, a distance and an acceleration and you are looking for the final velocity. Is there is a SUVAT equation to do that? What can you say about the velocity in the X direction? will it change? (I think it's safe to assume no air resistance acts) [/QUOTE]
