What is the electrical force between q1 and q2? recall that k = 8.99 × 109 n•meters squared over coulombs squared.. 4.3 × 10 n 3.5 × 10 n –5.4 × 10 n –5.8 × 10 n?

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?
