Hello, I'm asking this question for a second time because the answer I got for the first time was so poor. So please, if you answer this, then please provide an EXPLANATION, not simply a list of formulas with number plugged in.

Here is the question: A wooden boxcar is moving along a straight railroad track at speed v1. A sniper fires a bullet (initial speed v2) at it from a high powered rifle. The bullet passes thought both lengthwise walls of the car, its entrance and exit holes being exactly opposite each other as viewed from within the car. From what direction, relative to the track, is the bullet fired from? Assume that the bullet is not deflected upon entering the car, but that its speed is decreased by 20%. Take v1 to be 85 km/h and v2 = 650 m/s.

I know the answer is 93 degrees. However, that is all I know. I don't even know how to begin setting up this problem. So a step-by-step guide on how to solve this problem is needed.
