A test rocket is fired vertically from a well. A catapult boosts it to ground level, where it has a vertical velocity of 60.0 m/s. At ground level, the rocket engine fires, and the rocket accelerate upward with an acceleration of 5.00 m/s2. When the rocket is 800 m above the ground the engine fails, and the rocket goes into free fall, with a downward acceleration of 9.80 m/s2. Eventually, the rocket crashes into the earth's surface. (a) How long is the rocket in motion above the ground? (b) What is the maximum altitude reached by the rocket? (c) What is its velocity when it crashes into the ground?

At point A, the rocket is moving upward and leave ground level.
At point B, the engine falls and the rocket is still moving upward.
At point C, the rocket reaches its maximum height.
At point D, the rocket falls down to the ground level.

Escape velocity. We suppose that r = -gR^2/r^2. Suppose that a rocket is fired straight up, from the surface of the Earth with a velocity that is exactly half of the escape velocity. How high will the rocket go?

In rocket science, heat transfer issues must be addressed. Use the attached pictures to become familiar with the basic design of a rocket. The heat from the inside of the throat wall travels to the outside of the throat wall by conduction.

A rocket, which is in deep space and initially at rest relative to an inertial reference frame, has a mass of 265*10^105 kg, of which 200*10^5 kg is fuel. The engine is fired for 250s, during which fuel is consumed at the rate of 480 kg/s. The speed of the exhaust product relative to the rocket is 3.23 km/s.

A Saturn V rocket has a mass of 2.75 x 10^6 kg and exerts a force of 33 x 10^6 N on the gases it expels. Determine (a) the initial vertical acceleration of the rocket, (b) its velocity after 8 seconds, and (c) how long it takes to reach an altitude of 9500m. (Ignore the mass of gas expelled and assume g remains constant.)

A rocket is modelled by a particle that moves along a vertical line. From launch, the rocket rises until its motor cuts out after 13 seconds. At this time it has reached a height of 490 metres above the launch pad and attained an upward velocity of 70ms−1. From this time on, the rocket has a constant upward acceleration of −

Suppose a shuttle were launched from a launchpad on the Moon instead of the Earth's surface. What changes would we observe?
Suppose it were launched from a launchpad in space in vacuum. Would it work? What changes would we observe? Explain your answer.

A rocket is fired vertically upwards with initial speed V and is propelled by ejecting material downwards at a constant rate and with a constant speed u relative to the rocket. After a time T the propellant material is exhausted and the rocket still rising. Neglecting

Problem # 4 - The rocket is traveling in a free-flight elliptical orbit about the earth such that e = 0.76 and Its perigee is 9Mm as shown. Determine its speed when it is at point B. Also determine the sudden decrease in speed the rocket must experience at A in order to travel in a Circular orbit about the earth.
