Question

A run-away train engine with 10100 kg and coasts with a speed of 1.204 m/s. You are near-by hunting elk with your high power rifle and decide to shoot head-on to slow, even stop the train. The mass of your bullet is 143 g and is fired with a muzzle velocity of 3209 feet per second. To what speed is the train slowed just after the inelastic impact of the high power projectile? Work in groups of three on this problem, record your answer to paper, and turn this is when the polls close today. Allow in your sketch the bullet to go from the left to right (in a positive direction) and the train is going from right to left (negative direction).
A. -1.19 m/s B. 1.204 m/s C. 0.75 m/s D. -12.471 m/s E. None of these answers are correct. A run-away train engine with 10100 kg and coasts with a speed of 1.204 m/s.

Explanation / Answer

1 ft/s = 0.3048 m/s

Let the velocity after collision be v m/s

let the conservation of momentum we have

10100*-1.204 + 0.143*(3209*0.3048) = (10100 + 0.143) *V

V = -1.19 m/s

Option A) is the correct answer
