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 through 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? Assume that the bullet is not deflected upon entering the car, but that its speed decreases by 20%.Take v1 85 km/h and v2 650 m/s. (Why don’t you need to know the width of the boxcar?)

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 through 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? Assume that the bullet is not
deflected upon entering the car, but that its speed decreases by
20%.Take v1 85 km/h and v2 650 m/s. (Why don’t you need to
know the width of the boxcar?)
