rocket follows newtons third law of motion.
the thrust due to the fuel give the force to move forward.
The rocket used for the human lunar missions was the Saturn V rocket. At liftoff the mass of the rocket was 2.80 x 106 kg and the thrust of the five F1 engines is 3.45 x 107 N. (a) Draw the force diagram of the rocket. (b) What is the initial acceleration of the spacecraft? (c) The rocket uses 1.81 x 105 kg of fuel per second. What would be the acceleration of the mass of the rocket 0.5 and...
Rocket A leaves a space station with a speed of 0.80c. Later, rocket B leaves in the same direction with a speed of 0.50c. What the velocity of rocket A is as observed from rocket B?
Rocket A leaves a space station with a speed of 0.80c. Later, rocket B leaves in the same direction with a speed of 0.50c. What the velocity of rocket A is as observed from rocket B?
A small rocket is attached to a stiff wire as shown. The rocket
rests on a frictionless table. At t=0, the rocket is lit, and it
produces a thrust magnitude F. Note that the Thrust is not
tangential to the circular trajectory. At t=0, the rocket is at
rest.
a) What is the angular velocity after 2 revolutions?
b) What is the magnitude of the force by the wire after 2
revolutions?

At launch, the new rocket became the most powerful rocket in operation. It is capable of producing 5 million pounds of thrust (about 2.22 × 107 newtons). At launch, the rocket has a mass of about 1.42 × 106 kg. Estimate the acceleration of the rocket while it is still near the surface of the Earth and its engines must work against Earth's gravitational force. 2.
A rocket travels horizontally, close to the earth. The centripetal acceleration of the rocket is the earth's gravity (9.8 m/s2). If the earth's radius is 6.3 x 106 m and we neglect air resistance, how fast must the rocket be going to keep a constant height above the earth's surface?

A rocket expels exhaust at a rate of 50 m/s for 50 seconds. The rocket weighs 15,000 kg when empty. The rocket can hold 120,000 kg of fuel. At rest, weightless: 1. What speed is the rocket traveling when all the fuel is gone 2. How fast is the rocket traveling when only 30,000 kg of fuel has been used 3. When the rocket reaches 40 m/s how much fuel is left
A 10.0 kg rocket produces a thrust of 150 N. The rocket is pointed upward and the bottom of the rocket is attached to, and is resting on, a spring with a spring constant of 305 N/m. If the spring compressed 0.321 m prior to launch, what is the rocket's speed when the rocket is launched and the spring has stretched 0.417 m? clear steps please
A rocket has a weight of 263,000 Ibs on earth. If the rocket is on the moon, where the acceleration of gravity is gm 5.30 m/sec2, determine its weight and mass on the moon in SI units.
