Suppose a pulsar of mass 1.5x10^30 kg and radius 20km is spinning at the rate of 2.1 rev/s and is slowing down at the rate of 1x10^-15 rev/s.

A) What is the rate in J/s at which the rotational energy is decreasing?

B) If the rate of decrease is constant, what how long will it take the pulsar to come to a stop?
