Question

A pulsar is a rapidly rotating neutron star that emits radio pulses with precise synchronization, there being one such pulse for each rotation of the star. The period T of rotation is found by measuring the time between pulses. At present, the pulsar in the central region of the Crab nebula has a period of rotation of T = 0.16000000 s, and this is observed to be increasing at the rate of 0.00000943 s/y. What is the angular velocity of the star?

39.27 rad/s

b)What is the angular acceleration of the pulsar?

-7.334*10^-11 rad/s^2

c)If its angular acceleration is constant, in how many years will the pulsar stop rotating?

d)The pulsar originated in a super-nova explosion in the year A.D. 1054. What was the period of rotation of the pulsar when it was born?

I need c, d please show all the work from where you get the numbers al please the formulas i need them for my exam.
