Hey sorry just a quick thing here, we're actually doing this in school like atm in physics so i am not just, ... targeting people, Above the monk said:
F = MA (for the y-axis)
A = 1/23 m/s^2
V = U + AT
V = U + 13/46 m/s
right... normally no problems but I like accurate data.
v = u + at is wrong because that will really muck up the result using it raw.
v = u + a[delta]t
because its change in time, where U is the velocity when time was current time - [delta]time
sorry for using delta but I don't know where the triangle symbol is
Delta means change in
and the correct expression is ms-1 or ms-2 for acceleration
For anyone doing this at home, or not really understanding them, the actual result is in distance units per time unit
so if your distance is meters and time seconds meters per second -> m/s -> ms-1
this is just units / frame -> uf-1 presumably
To convert frames to seconds its 1 / screen fps() which is fine, unless it lags and screen FPS is zero, then DB will crash and say "div by zero at line x" so... heads up there.
Havok
hope i helped someone
also a good page for Equations of Motion
http://en.wikipedia.org/wiki/Equations_of_motion
there, now that you know a triangle means delta which means change in you should be fine, the little subscript i means initial so v and a little i is initial velocity, but this is often just called "u"
lastly i don't know why s means displacement, (distance basically)
