ch10 p 32 9th addition fundamentals of physics.
A pulsar is a rapidly rotating neutron star that emits a radio beamthe way a lighthouse emits a light beam. We receive a radio pulsefor each rotation of the star. The period T of rotation is found bymeasuring the time between pulses. Suppose a pulsar has a period ofrotation of T = 0.0841 s that is increasing at the rate of 2.16 x10-6 s/y. (a) What is the pulsar's angular acceleration ? (b) If isconstant, how many years from now will the pulsar stop rotating?(c) Suppose the pulsar originated in a supernova explosion seen1160 years ago. Assuming constant , find the initial T.
