Welcome to European Tribune. It's gone a bit quiet around here these days, but it's still going.
speed can be vectored as horizontal and vertical components and thus the angle of impact isn't really important

as for the impacted medium, I have already told you that that was a variable, but if you know it's physical properties, you can extrapolate from one medium to another
