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. Suppose a pulsar has a period of rotation of T=0.0231 s that is increasing at the rate of 4.76 x 10 s/y. (a) What is the pulsar's angular acceleration a? (b) If a is constant, how many years from now will the pulsar stop rotating? (c) Suppose the pulsar originated in a supernova explosion seen 894 years ago. Assuming constant a, find the initial T. (a) Number i 1.8*10^-10 Units rad/s^2 (b) Number 484221 (c) Number i 000013 Units Units years
