One of the first ion engines on a commercial satellite usedXenon as a propellant and could eject the ionized gas at a rateof 3.03 x 1026 kg/s with an exhaust speed of 3.04 x 104 m/s.What instantaneous thrust could the engine provide?

The Merlin rocket engines developed by SpaceX can produce 7.12 ✕ 105 N of instantaneous thrust with an exhaust speed of 3.05 ✕ 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.)

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

If a rocket engine ejects gases at a rate of 29 kg/s, how fast must the gaseous exhaust be moving if the thrust produced is sufficient to allow a 2.7 x 105 kg rocket to rise slowly from the earth when aimed straight up? Express your answer in km/s.

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.)
