Is it possible for the velocity of a rocket to be greater than the exhaust velocity...
Homework Answers
Yes, I think that is pretty much possible. A rocket can have velocity greater than the exhaust velocity of the gases. The reason for this is conservation of momentum.The thrust of the rocket does not depend on the relative speed between the gases and rocket but rather on the product of mass and velocity.

Timer |-]Notes à Evaluate a Feedback-Print 61nfo Course Contents » » Rocket Leaving Solar System Alt Version Due this Friday, Oct 12 at 08:15 am (EDT) A rocket is moving away from the solar system at a speed of 5.20x103 m/s. It fires its engine, which ejects exhaust with a velocity of 2.80x103 m/s relative to the rocket. The mass of the rocket at this time is 4.20x104 kg, and it experiences an acceleration of 3.20 m/s2. What is the...

Combustion Nozdc Exhaust Fud Exit - V - Velocity m- mass flow rate p- pressure Throat 2.4 kg/s of liquid hydrogen and 24 kg/s of liquid oxygen enter a rocket engine where they are supposed to combust. A large leak in the combustion chamber allows 13 kg/s of the mixture to escape prior to combustion. (Assume that the leak is composed of the same proportion of Hz and Oz as flow into the engine.) The remaining gases combust, and the...

Pulley A rotates clockwise at a constant angular velocity, driving a second larger Pulley B using a flexible belt moving around the two pulleys without slipping. The radius r_A for Pulley A is half of the radius r_B of Pulley B. Is the magnitude of the angular velocity of Pulley A greater than, less than, or equal to the magnitude of the angular velocity of Pulley B? Explain. Is the magnitude of the linear velocity of a point on the...

Colby participates in a rocket-launch competition in her high school. The goal is to launch a rocket with mass m = 2.3 kg [5 lbs] to a height no less than 50-m (164 ft) above ground. a) What is the minimum momentum of the rocket as it leaves the launch pad? b) Colby figured out three possible propulsion mechanisms that differ by the generated force F (“thrust”) and the time interval ∆t during which the force acts on the rocket...

What happens to the acceleration and velocity of an Apache helicopter when it fires a rocket-propelled missile at an enemy tank in front of it? How about the torque exerted by the missile? After launching a missile, will the helicopter's speed be faster, slower, or stay same? Does the pilot have to correct for pitch, yaw, or roll? Provide your reasoning. What parameters would you need to figure those accelerations?
