A pulsar is a rapidly rotating neutron star that emits radio pulses, one such pulse for each rotation of the star. The period T of rotation is the time for one rotation. It 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 = 0.033 s, and this is observed to be increasing at the rate of 1.26 x 10-5 s/y. What is the value of the angular acceleration in rad/s2? If its angular acceleration is constant, how many years from now will the pulsar stop rotating? The pulsar originated in a supernova explosion seen in the year A.D. 1054. What was T of the pulsar when it was born? (Assume constant angular acceleration since then.)

Definition Definition Rate of change of angular velocity. Angular acceleration indicates how fast the angular velocity changes over time. It is a vector quantity and has both magnitude and direction. Magnitude is represented by the length of the vector and direction is represented by the right-hand thumb rule. An angular acceleration vector will be always perpendicular to the plane of rotation. Angular acceleration is generally denoted by the Greek letter α and its SI unit is rad/s 2 .
