Chapter , Problem 18(choose chapter or problem)
A pulsar is a rapidly rotating neutron star that emits a radio beam the way a lighthouse emits a light beam. We receive a radio pulse for each rotation of the star.The period T of rotation is found by measuring the time between pulses. The pulsar in the Crab nebula has a period of rotation of T ! 0.033 s that is increasing at the rate of 1.26 $ 10%5 s/y. (a) What is the pulsars angular acceleration a? (b) If a is constant, how many years from now will the pulsar stop rotating? (c) The pulsar originated in a supernova explosion seen in the year 1054.Assuming constant a, find the initial T
