2. A rocket of mass m is fired vertically from the Earth, with an initial speed U. It rises to a height R/2 before falling back to Earth, where R is the radius of the Earth. Calculate U in terms of G, M (the Earth's mass) and R. The rocket is fired with the same initial speed, but this time at an angle 45° to the horizontal. Calculate its angular momentum J and total energy E, and use these to...

A rocket is launched vertically upward from Earth's surface at a speed of 5.4 km/s . What is its maximum altitude? Express your answer using two significant figures. = m
Planet A with mass Ma = 1.90 times 10^27 kg and radius R.t = 71.5 times10^6 m is located at the origin of a coordinate system. A rocket with mass m_r = 2.02 times 10^6 kg is shot up from the surface of planet A along the y axis with initial velocity v = 30.00 km/s What is the maximum height h the rocket reaches above the surface of planet A? What is the acceleration vector a (vector notation) of...
A test rocket is fired vertically upward from a well. A catapult gives it an initial speed of 80.2 m/s at ground level. Its engines then fire and it accelerates upward at 3.80 m/s2 until it reaches an altitude of 930 m. At that point its engines fail, and the rocket goes into free fall, with an acceleration of -9.80 m/s2. (You will need to consider the motion while the engine is operating separate fronm the free-fall motion.) (a) How...
As a spacecraft approaches a planet, the rocket engines on it are fired (turned on) to slow it down so it will go into orbit around the planet. The spacecraft's mass is 2,275 kg and the thrust (force) of the rocket engines is 465 N. If its speed must be decreased by 1,259 m/s, how long (in minutes) must the engines be fired? (Ignore the change in the mass as the fuel is burned.)
A rocket, launched from the Earth, shuts off its engines when its speed is 5.40 km/s. It reaches a maximum altitude of 2820 km before it falls back to Earth. At what altitude did the rocket's engines shut off? The mass and radius of the Earth are 5.97 10^24 kg and 6.37 10^6 m, respectively.
You are exploring a distant planet. When your spaceship is in a circular orbit at a distance of 630 km above the planet's surface, the ship's orbital speed is 5200 m/s. By observing the planet, you determine its radius to be 4.48×106m. You then land on the surface and, at a place where the ground is level, launch a small projectile with initial speed 11.6 m/s at an angle of 30.8∘ above the horizontal. a)If resistance due to the planet's...
A projectile is fired vertically from Earth's surface with an initial speed of 4.0 km/s. Neglecting air drag, how far above the surface of Earth will it go?
