Homework Help: Finding angular acceleration

  1. Feb 5, 2013 #1
    Hi everyone!

    I have a question about tangential acceleration:

    A pulsar is a rotating neutron star which sends out radio pulses with precise time intervals. Every time the star rotates a pulse is received. The period, T, is measured by measuring the time intervals between the pulses. Today the pulsar has a rotation period T = 0,033 s and the period increases with 1,26 x 10-5 s per year.

    How big is the angular acceleration?

    Thanks everyone for taking a look at this! :)

    What are the units of angular and tangential velocity?
