A4.33 kg ball is dropped from the roof of a building 157.2 m high. while the ball is falling to earth, a horizontal wind exerts a constant force of 11.5 n on the ball. how long does it take to hit the ground? the acceleration of gravity is 9.81 m/s 2 . answer in units of s.

In a load, the load is paralel to the shaft. n a. angular n b. thrust n c radial n d. none of the above

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
