Motor oil , with a viscosity of 0 . 250 ns / m2 , is flowing through a tube that has a radius of 5 . 00 mm and is 25 . 0 cm long . the drop in pressure is 300 kpa . what is the volume of oil flowing through the tube per unit time ?

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
