Pulsars. When a star with a mass at least ten times that of the Sun explodes outward in a supernova, its core can be collapsed into a
pulsar, which is a spinning star that emits electromagnetic radiation (radio waves or light) in two tight bears in opposite directions. If a
beam sweeps across Earth during the rotation, we can detect repeated pulses of the radiation, one per revolution. (a) The first pulsar
was discovered by Jocelyn Bell Burnell and Antony Hewish in 1967; its pulses are separated by 1.3373 s. What is its angular speed in
revolutions per second? (b) To date, the fastest spinning pulsar has an angular speed of 716 rev/s. What is the separation of its detected
pulses in milliseconds?

C6M.9 Astar with mass M and radius R collides with another
star of massM and radius R, and coalesce to form a new
star at rest whose radius is R. Assume that initially the
colliding stars had angular velocities with opposite direc-
tions but the same magnitude | What is the magnitude
and direction of the final star's angular velocity? (Express
the magnitude as a fraction of )
A star has a mass of 1.5 x 10^30 kg and is moving in a circular orbit about the center of its galaxy. The radius of the orbit is 2.2 x 10 ^ 4 light years( 1 lightyear = 9.5 x 10 ^15 m ) , and the angular speed of the star is 2.2 x 10 ^ -15 rad/s. a) Determine the tangential speed of the star. b) What is the magnitude of the net force that acts on the star to keep moving around the center of the galaxy?
