Why not just, every frame, move the ball a certain amount x, and add a certain amount to the amount the ball gets moved y?
eg:


System Specs: AMD Athlon 1700+ XP, GA-7VRX motherboard, 128MB DDR RAM, GeForce2 MX400 64MB VRAM

this line
ballx# = vix# * time# + 0.5 * 0 * sqrt(time#)
can become
ballx# = vix# * time#
as the rest of it will always be zero, as there is zero acceleration in the x plane.

and also the equation you seem to be using is S=UT+0.5AT^2
So the other line should in fact read
bally# = viy# * time# + 0.5 * -10 * (time#)^2

hope this is helpfull.

Specs:- 1GHZ athlon, Radeon8500, 192mb ram, winxp
