Chapter 2, Problem 25P
. 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 2.000 kg, and the thrust (force) of the rocket engines is 400 N. If its speed must be decreased by 1,000 m/s, how long must the engines be fired? (Ignore the change in the mass as the fuel is burned.)

Recently, the Amazon and Virgin groups launched commercial space flights. These flights do not store fuel on board, instead, they inhale oxygen from the air. If the weight of one of these new rockets is 2420 kN, while a regular rocket is 19579 kN, what would be the acceleration of these two rockets close to the Earth's surface when a thrust of 25467 kN is applied?
A rocket has an initial mass of 29,000 kg, of which 20% is the payload. It burns fuel at a rate of 175 kg/s and exhausts its gas at a relative speed of 1.8 km/s.
a) Find the thrust of the rocket.
Solved: 315 kN
b) Find the time until burnout.
Solved: 132.57 s
c) Find the rocket's final speed (in km/s) assuming it moves straight upward near the surface of Earth where the gravitational field g is constant.
