A quick look through the FAQ and search didn't reveal anything so... I know that K.e. = ½MV², however I am looking to find the energy of an impact when φ != 90°. Or to the more specific problem, if I have a Spaceship shaped like a needle moving through space at .9c(Vnet) and a micrometor hits it with a mass of 1g(M) and the angle between the metorite and the hull is 10°, how much energy would the ship absorb. This is not a homework question, which is why I didn't post it there...sorry should have posted that before the moderator moved it.
