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?

An airplane is heading due south at a speed of 620 km/h . part a: if a wind begins blowing from the southwest at a speed of 90 km/h (average), calculate the velocity (magnitude) of the plane relative to the ground. [hint: first draw a diagram.] express your answer to three significant figures and include the appropriate units. part b: calculate the velocity (direction) of the plane relative to the ground. express your answer to three significant figures and include the appropriate units. part c: calculate how far from its intended position will it be after 14 min if the pilot takes no corrective action. express your answer to three significant figures and include the appropriate units.

(a) calculate the number of electrons in a small, electrically neutral silver pin that has a mass of 10.0 g. silver has 47 electrons per atom, and its molar mass is 107.87 g/mol. (b) imagine adding electrons to the pin until the negative charge has the very large value 1.00 mc. how many electrons are added for every 109 electrons already present Physics, 22.06.2019 11:30
