Many star are observed to have rotation periods that lengthenslightly with time, a phenomenon called "spin down." The rate ofslowing of the Crab Star is 3.50*10-13 s per second, which implies that if thisrate remains constant, the Crab Comet will stop spinning in9.50*1010 s (about 3000 years from today). What is the tangential acceleration of an object on the equator ofthis star?
