A toy rocket with a mass of 300 g takes off in an upward vertical direction under the influence of thrust and gravity. It burns fuel at the rate of 25 g/s. The exhaust speed of the gas is 80 m/s. What is the speed of the rocket at the end of 10 seconds? (g = 9.8 m/s²)

NASA's Saturn V rockets that launched astronauts to the moon were powered by the strongest rocket engine ever developed, providing 6.77 x 10° N of thrust while burning fuel at a rate of 2.63 x 103 kg/s. Calculate the engine's exhaust speed (in m/s). HINT m/s Need Help?

A new design of Saturn 10 rocket with mass 1.95 x106 kg has a propulsion engine that can eject gases at a constant speed of 314.9 m/s (vGas) by burning fuel at a rate of 4.38  x10 5  kg/s (dmdT). In full tank, the rocket can carry a fuel of mass 43.2  x10 6  kg. If this design exceeds the velocity of 11,200 m/s it can can successfully escape Earth's gravity. Determine if this is so. Find its maximum velocity (velyZ). (Pitch Angle = 0)
