Two manned satellites approaching one another at a relative speed of 0.300 m/s intend to dock. The first has a mass of 2.50 ✕ 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? 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. ....................m/s

A 3 kg asteroid is moving way out in space with velocity 3î – 2ĵ + 7k ms1. It collides with an asteroid of mass 7 kg moving with velocity -3î + 2ĵ – 7k ms1. The two stick together. - Determine the velocity vector of the resulting larger asteroid after the collision.

A particle with mass mA = 3.00 kg is located at  rA = (2.50 i + 3.50 j) m, and a second particle of mass m2B = 5.00 kg is located at  rB = (1.50 i – 3.00 j) m.  Find the location of the center of mass of the system relative to the point (1,1).

Two astronauts, of masses 56.4 kg and 71.5 kg, are initially right next to each other and at rest in outer space. They suddenly push each other apart. How far has the heavier astronaut moved when the lighter astronaut has moved 14.5 m?

A rocket, which is in deep space and initially at rest relative to an inertial reference frame, has a mass of 86.2 × 105 kg, of which 14.7 × 105 kg is fuel. The rocket engine is then fired for 180 s, during which fuel is consumed at the rate of 480 kg/s. The speed of the exhaust products relative to the rocket is 2.98 km/s. (a) What is the rocket's thrust? After the 180 s firing, what are (b) the mass and (c) the speed of the rocket?
