# Physics

A pulsar is a rapidly rotating neutron star that continuously emits a beam of radio waves in a searchlight manner. Each time the pulsar makes one revolution, the rotating beam sweeps across the earth, and the earth receives a pulse of radio waves. For one particular pulsar, the time between two successive pulses is 0.024 s. Determine the average angular speed (in rad/s) of this pulsar.

angular velocity= displacement/time= 2PI/time

solve for angular speed.

3.28 / 0.024 = 136.667 rad/s

I would list two sig figures, as .024 only has two. 1.37*10^2 rad/sec
