The speed of a bobsled is increasing, because it has an acceleration of 2.44 m/s2. At a given instant in time, the forces resisting the motion, including kinetic friction and air resistance, total 595 N. The mass of the bobsled and its riders is 315 kg. (a) What is the magnitude of the force propelling the bobsled forward

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?
