Ameteorite approaching a planet of mass m collides with an automatic space station orbiting the planet in a circular trajectory of radius r. the mass of the station is ten times as large as the mass of the meteorite . as a result of the collision, the meteorite sticks with the station which goes over to a new orbit with the minimum distance r/2 from the planet. speed of the meteorite just before it collides with the space station is

Acave rescue team lifts an injured spelunker directly upward and out of a sinkhole by means of a motor-driven cable. the lift is performed in three stages, each requiring a vertical distance of 10.0 m: (a) the initially stationary spelunker is accelerated to a speed of 4.90 m/s; (b) he is then lifted at the constant speed of 4.90 m/s; (c) finally he is decelerated to zero speed. how much work is done on the 68.0 kg rescue by the force lifting him during each stage?
