A 15,000 kg rocket traveling at +230 m/s turns on its engines. Over a 6.0 s period it burns 1,000 kg of fuel. An observer on the ground measures the
velocity of the expelled gases to be -1,200 m/s.
b. What is the acceleration of the rocket during the burn? Express your
answer in "g's.
Please answer ASAP :) thank you
