A0.0600-kilogram ball traveling at 60.0 meters
per second hits a concrete wall. what speed
must a 0.0100-kilogram bullet have in order to
hit the wall with the same magnitude of
momentum as the ball?
(1) 3.60 m/s (3) 360. m/s
(2) 6.00 m/s (4) 600. m/s

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?
