A5.0-kg centrifuge takes 95 s to spin up from rest to its final angular speed with constant angular acceleration. a point located 6.00 cm from the axis of rotation of the centrifuge with a speed of 99 m/s when the centrifuge is at full speed moves (a) what is the angular acceleration (in rad/s2) of the centrifuge as it spins up? (b) how many revolutions does the centrifuge make as it goes from rest to its final angular speed?

The sun’s mass is 2.0×10^ 30 kg, its radius is 7.0×10 5 km, and it has a rotational period of approximately 28 days. if the sun should collapse into a white dwarf of radius 3.5×10 3 km, what would its period be if no mass were ejected and a sphere of uniform density can model the sun both before and after?
