A 2kg ball is attached to a ceiling by a string. The distance from the ceiling to the center of the ball is 1.0m, and the height of the room is 3.0m. What is the potential energy associated with the ball relative to each of the following:
a. the ball relative to the ceiling?
b. the ball relative to the floor?
c. the ball realtive to a point at the same elevation as the ball?

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?

A10nc charge sits at a point in space where the magnitude of the electric field is 1500 n/c. what will the magnitude of the field be if the 10 nc charge is replaced by a 20 nc charge? assume the system is big enough to consider the charges as small test charges.
