HELP ASAP PLS A locomotive with a rocket engine is being tested on a smooth horizontal track. The mass of the

locomotive is unknown. Starting from rest, the engines are fired for 20 s. During this time

they expel 500 kg of oxidized kerosene. The kerosene particles are expelled at an average

velocity of 1200 m/s. At the end of the 20-s period the speed of the locomotive is 50 m/s.

What is its mass?
