The Merlin rocket engines developed by SpaceX produce8.01 x 105 N of instantaneous thrust with an exhaust speed of3.05 x 103 m/s in vacuum. What mass of fuel does the engineburn each second?

A Saturn V rocket was measured to produce exit gases with a velocity of 2000m/s whenconsuming 1500 kg/s of fuel and oxygen. Calculate the thrust.

ASAP PLS SHOW ALL WORK In the movie “The Martian”, an astronaut needs to propel himself through space to get to a spaceship. He attempts to do this by puncturing the glove in his spacesuit, which contains 3.00 kg of air under pressure. He is initially at rest, with a mass (including the spacesuit and air) of 75.0 kg. If the air comes out at 28.0 m/s at a constant rate, what final speed does he reach when the air is used up?

The Merlin rocket engines developed by SpaceX can produce 7.44 x 105 N of instantaneous thrust with exhaust speed of 3.05 x 10³ m/s in vacuum. What mass of fuel does the engine burn each second to produce this thrust? (Enter your answer in kg/s.) HINT kg/s

Ion-propulsion rockets have been proposed for use in space. They employ atomic ionization techniques and nuclear energy sources to produce extremely high exhaust velocities, perhaps as great as 8.00 ✕ 106 m/s. These techniques allows a much more favorable payload-to-fuel ratio. To illustrate this fact: (a) Calculate the increase in velocity in m/s of a 23,000-kg space probe that expels only 40.0-kg of its mass at the given exhaust velocity.   m/s (b) These engines are usually designed to produce a very small thrust for a very long time—the type of engine that might be useful on a trip to the outer planets, for example. Calculate the acceleration in m/s2 of such an engine if it expels 4.50 ✕ 10−6 kg/s at the given velocity, assuming the acceleration due to gravity is negligible.   m/s2

A 4.8-g bullet leaves the muzzle of a rifle with a speed of 326 m/s. What force (assumed constant) is exerted on the bullet while it is traveling down the 0.81-m-long barrel of the rifle? Need Help? Watch It Read It MY NOTES AS PREVIOUS ANISWERS SERCP11 4.6.P.040.

I would appreciate some hwlp with this question. Thanks!   A model rocket consisting of a 61.0-g chassis and a 30.5-g engine is taken on an interstellar mission and fired in outer space. The engine produces 5.00 N of thrust while expending 13.0 g of fuel at a constant rate during a 2.04-s burn. (Assume the mass of the engine includes the mass of the fuel.) (a) What is the average exhaust speed of this rocket's engine?   (b) If the rocket starts from rest, what is its final velocity? (Assume the thrust to be in the positive direction. Indicate the direction with the sign of your answer.)
