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 stone of mass 0.750 kg is launched vertically upward, from the ground, with an initial velocity of 18.0 m/s. (a) Determine the average power consumed by the gravitational force during the time it moves from the ground to 12.0 m above the ground? (b) Determine the instantaneous power being consumed by gravity when it first reaches 12.0 m above the ground?

1. A rocket is launched vertically from the Earth, and the thrust (pushing force) from the engines is directed upward, and has a magnitude of 5.00 x 106 N. The mass of the rocket is initially 2.00 x 105 kg. (a) What is the initial acceleration of the rocket, assuming you can neglect air resistance? (b) After the rocket has been in flight for a while, burning and exhausting a lot of fuel, its mass has decreased to 1.20 x 105 kg, and...

A rocket is launched from the Earth’s surface. Unfortunately, the engineers have miscalculated and the rocket runs out of fuel when its height is exactly one earth radii above the earth’s surface. The rocket immediately falls from rest back to toward the surface. Ignore friction and air resistance in your calculations. R subscript E equals 6.37 cross times 10 to the power of 6 space m e t e r s comma space M subscript E equals 5.98 cross times...

A 2590-kg test rocket is launched vertically from the launch pad. Its fuel (of negligible mass) provides a thrust force so that its vertical velocity as a function of time is given by v(t)=At+Bt2, where A and B are constants and time is measured from the instant the fuel is ignited. At the instant of ignition, the rocket has an upward acceleration of 2.00 m/s2 and 1.60 s later an upward velocity of 2.46 m/s . At 4.30 s after...

3. A SpaceX StarshipTM single-stage rocket is launched vertically from the moons surface. It burns k kg of fuel per second, so its mass as a function of time is m = mo - kt. Assume constant acceleration of gravity g and a constant exhaust speed of vex (a) By integrating with respect to time, calculate the rockets velocity versus time (while it still has fuel). (b) Integrate again to show that the altitude versus time is given by (e)...
