Hey /sci/ for some project we need to build a ski-jump to launch a round bullet as far as possible

when you know the speed when it leaves the ramp it's easy to get to the distance it travels,
but i'm having trouble finding a good formula to calculate the speed the bullet has right before it leaves the jump.
(i suppose an angle of 45° degrees is optimal)

[other factors is that its a inox/rustfree steel bullet with 1.5 cm diametres (0.6 inch) and that the ramp is 100cm (40inch) hifh max]
