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

To practice problem-solving strategy 10.1 for energy conservation problems. a sled is being held at rest on a slope that makes an angle θ with the horizontal. after the sled is released, it slides a distance d1 down the slope and then covers the distance d2 along the horizontal terrain before stopping. find the coefficient of kinetic friction μk between the sled and the ground, assuming that it is constant throughout the trip.
