What can we say about the speed and therefore the kinetic energy of a satellite in circular orbit. The speed is always increasing and so is the kinetic energy.

The speed and the kinetic energy of a satellite in orbit never changes since gravity does no work on a satellite.

The speed is decreasing and the kinetic energy is also decreasing.

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 11.0 m: (a) the initially stationary spelunker is accelerated to a speed of 4.80 m/s; (b) he is then lifted at the constant speed of 4.80 m/s; (c) finally he is decelerated to zero speed. how much work is done on the 78.0 kg rescue by the force lifting him during each stage
