Chapter 7, Problem 22P

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 10.0 m: (a) the initially stationary spelunker is accelerated to a speed of 5.0 m/s; (b) he is then lifted at the constant speed of 5.00 m/s; (c) finally he is decelerated to zero speed. How much work is done on the 80.0 kg rescuee by the force lifting him during each stage?

A 100 kg crate, starting from rest, is pulled across a floor with a constant horizontal force of 200 N. For the first 15 m the floor is frictionless and for the next 15 m the coefficient of friction is 0.15. * What is the final speed of the crate?

A cyclist coasts up a 12.1° slope, traveling 16.0 m along the road to the top of the hill. If the cyclist's initial speed is 8.90 m/s, what is the final speed? Ignore friction and air resistance.

A water slide is constructed so that swimmers, starting from rest at the top of the slide, leave the end of the slide traveling horizontally. As the drawing shows, one person hits the water 5.00 m from the end of the slide in a time of 0.627 s after leaving the slide. Ignore friction and air resistance, find the height H in the drawing.
