Chapter 8, Problem 52SP

(a)What minimum thrust must the engines of a 2.0 × 10 5 kg rocket have if the rocket is to be able to slowly rise from the Earth when aimed straight upward? (b) If the engines eject gas at the rate of 20 kg/s, how fast must the gaseous exhaust be moving as it leaves the engines? Neglect the small change in the mass of the rocket due to the ejected fuel. [Hint: Study Problem 8.20.]

If a rocket engine ejects gases at a rate of 29 kg/s, how fast must the gaseous exhaust be moving if the thrust produced is sufficient to allow a 2.7 x 105 kg rocket to rise slowly from the earth when aimed straight up? Express your answer in km/s.
One of the first ion engines on a commercial satellite usedXenon as a propellant and could eject the ionized gas at a rateof 3.03 x 1026 kg/s with an exhaust speed of 3.04 x 104 m/s.What instantaneous thrust could the engine provide?
Two manned satellites approach one another at a relative speed of 0.100 m/s, intending to dock. The first has a mass of 5.50 ✕ 103 kg, and the second a mass of 7.50 ✕ 103 kg. If the two satellites collide elastically rather than dock, what is their final relative velocity in meters per second? (Adopt the reference frame in which the second satellite is initially at rest and assume that the positive direction is directed from the second satellite towards the first satellite.)
