Answer: A wooden boxcar is moving along a straight
Chapter , Problem 119(choose chapter or problem)
A wooden boxcar is moving along a straight railroad track at speed \(v_{1}\). A sniper fires a bullet (initial speed \(v_{2}\)) 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 \(v_{1}\) = 85 km/h and \(v_{2}\) = 650 m/s. (Why don’t you need to know the width of the boxcar?)
