Hi,
I have a physics problem here that I'm quite stuck on. Maybe I'm making it harder than it seems:
A ball is thrown upward with an initial speed, Vo. When it reaches the top of its flight, at a height h, a second ball is thrown at the same initial velocity. Find the height where the paths cross.
No number values are given, so I'm thinking I should be using and manipulating the formula x=xo+vot+0.5at^2 to get a variable answer. I know xo is zero since that's the starting height of both balls and acceleration is gravity (9.81).
Also, I graphed (displacement vs time) the function assuming that the parabola is even and therefore max height is reached at 0.5 total time. And, the paths crossing would be at 3/4 total time...however, I'm not sure if that's theoretically right.
Any help would be great! Thanks
