Pulsars are astronomical objects that give off very regular pulses of radio waves with periods roughly between 1 ms and 1 s. A pulsar may form when a star of medium mass dies. Contemporary astronomers have measured the angular speed of a pulsar in the Crab Nebula as 1.89 x102rad/s and have found that the pulsar is slowing down such that its angular acceleration has a magnitude of 2.39 x10-9 rad/s2. What was the initial angular speed of the Crab Nebula ́s pulsar in 1054 when it was discovered? Assume a year has 365days.
