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! :)
