Atoy uses a spring to shoot an arrow with a suction cup on
the end. the toy shoots a 34.2 g arrow and gives it a speed of
5.50 m/s. if the efficiency of the toy is 69.0%, how much elastic
potential energy was stored in the spring? show all your work.

Asatellite with an orbital period of exactly 24.0 h is always positioned over the same spot on earth. this is known as a geosynchronous orbit. television,communication, and weather satellites use geosynchronous orbits. at what distance would a satellite have to orbit earth in order to have a geosynchronous orbit?
