## Homework Statement

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 0.00000506 s/y.

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

already found

angular acel to be -3.935x10^-11 rad/s^2

wf = 39.269

wi = 39.2699

## Homework Equations

## The Attempt at a Solution

Im stumped as to how to find this, i had initially tried to use wf = wi + angular accel*t thinking that the t i solved for would be the value i wanted.

i did 39.269 = 39.2699+ -3.935x10^-11t

that gave me 31559593.39 seconds then i did conversions to turn s into yrs which was that /60 s /60 min/24 hr/365d = 1.0007 yrs which is way to small it should be thousands of years shouldnt it.
