In billiards, collisions occur between pool balls as they make contact with one another. In one particular collision, when all balls are
initially at rest, a white ball is struck with a stick and makes contact with a red ball. The table below summarizes the motion of the
white ball, with t = 0 when the white ball is initially struck by the pool stick.

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
