A cave 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 meter:
(a) the initially stationary spelunker is accelerated to a speed of 5.00 m/s;
(b) he is then lifted at the constant speed of 5.00 m/s:
(c) finally he is decelerated to zero speed. Find how much work is done on the 80.0 kg rescue by the force lifting him during each stage?
A 80 kg man is ice-skating due north with a velocity of 6.0 m/s when he collides with a 35 kg child. find the magnitude of the child's velocity just before the collision
