1. The problem statement, all variables and given/known data The record for spitting a watermelon seed by a man is 68.75 feet. Assuming he spat at an angle of 45.0 degrees and from an initial height of 1.50 meters above the ground, how fast did he spit the seed out of his mouth. (neglect any air resistance) 2. Relevant equations The only equations I know are basic kinematic equations. No mass/force stuff. Some of the equations we use are: d-d0 = V0t + 1/2at^2 V = V0 + at V^2 = V0^2 + 2a(d-d0) That's pretty much it. The 0's should be subscripts, but I don't know how to do that. 3. The attempt at a solution I know how to solve for the time it takes to reach its max height (t=(V0sin45)/(a)), but from there I am stuck. For the time it takes to go down from its max height, I know what V0 is and I know what a is, but that's it, so I don't know how to solve for that. I think if I'm going to get initial velocity I first need 3 other variables. And unless I get time, I can't have 3, right? I don't just want the answer, because that doesn't really help me at all. A simple explanation (I've only been in Physics for less than 4 months) would be very helpful.
