A one-stage rocket takes off from Space and is tasked with entering into a geosynchronous (the

period of orbit is one day) low earth orbit at an altitude of 2,000km above the surface of the Earth. The mass of the

rocket is 550,000kg,

a) At what final speed does the rocket need to be moving to achieve the specified orbit?

b) If the exhaust velocity of the fuel is 2.20x103m/s what percentage of the rocket’s mass must be fuel?

c) Given that the rocket expends fuel at a rate of 1.4x104kg/s would this rocket be appropriate for manned flights?

A rocket takes off vertically from the launchpad with no initial velocity but a constant upward acceleration of 2.5 m/s^2. At 10 s after takeoff, the engines fail completely so the only force on the rocket from then on is the pull of gravity. A) What is the maximum height the rocket will reach above the launchpad? B) How long after engine failure does it take for the rocket to crash back down?

In the first stage of a two-stage rocket, the rocket is fired from the launch pad starting from rest but with a constant acceleration of 3.50 m/s2 upward. At 25.0 s after launch, the second stage fires for 10.0 s, which boosts the rocket’s velocity to 132.5 m/s upward at 35.0 s after launch. This firing uses up all the fuel, however, so after the second stage has finished firing, the only force acting on the rocket is gravity. Air...

A model rocket blasts off from the ground, rising straight upward with a constant acceleration that has a magnitude of 91.3 m/s2 for 1.79 seconds, at which point its fuel abruptly runs out. Air resistance has no effect on its flight. What maximum altitude (above the ground) will the rocket reach?

Some time, delta T, after a rocket blasts off from the surface of earth, it is travelling at a constant speed, and its instantaneous mass(including fuel) is M+20,000kg. The gas ejected out the back of the rocket is moving at a relative velocity of 1,200 m/s (downward), with respect to the rocket. You may assume that the rocket is still very close to the surface of the earth, and that air resistance is negligible. A) What is the rate of...
