Projectile Motion, Shooting a Ball in Zero Gravity. URGENT! So I had to come up with my own problem for class, but this is going to be in zero gravity. I chose lacrosse. 1. The problem statement, all variables and given/known data Chris Fiore does a split dodge with the help of a pick and gets his hands free for a sidearm shot from 15 yards. He is so good that when he shoots, the ball always travels in a 2D path! The initial velocity of the shot is 96mi/h (Chris Fiore is one of the fastest shooters in lacrosse). How long does it take until it hits the goal? 2. Relevant equations Conversions: 15yd (0.91m) = 13.72m 96mi/h(1609.34m)(3600s) = 5.56x108m/s d = vit + 1/2gt2 3. The attempt at a solution If this is how it is calculated on Earth... d = vit + 1/2gt2 13.72 = (5.56x108)t + 0.5(-9.81) t2 -4.91t2 + 5.56x108x -13.72 = 0 t = 2.47s What the hell happens if the gravity is zero? I can't just put in 0 instead of -9.81 can I? From what I recall the whole formula doesn't even work if its not on earth! The ball would go insanely fast! Need some clarification on this. How would I go about calculating this? Thanks!
