A star with an initial radius of 1.0 x 108 m and a period of 30.0 Earth days collapses suddenly to a radius of 1.0 x 104 m, while keeping essentially the same mass. This collapsed star is probably a neutron star.

(a) What will be the angular velocity of the neutron star in rad/s and rot/s?

(b) What will be the speed, in m/s of an indestructible person standing on the equator of the neutron star?

(c) What per cent of the speed of light will the person be traveling on the neutron star?

A certain star of radius 6.34 million meters, rotates twice around its axis in one earth day. Find its angular frequency. This star has a mass of 1.00x1032 kg. When this star collapses to a neutron star, its radius shrinks by a factor of 104 while it loses 30% of its mass. Find the angular velocity of this star after the collapse. Assume that the spherical shape and density of the star remain unchanged . Find the speed and centripetal...

Calculate the density of a neutron star with a radius 1.7 x 104 m, assuming the mass is distributed uniformly. Treat the neutron star as a giant nucleus and consider the mass of a nucleon 1.675 x 10-27 kg. Your answer should be in the form of N x 1017 kg/m3. Enter only the number N with two decimal places, do not enter unit.

A flat uniform circular disk (radius = 3.00 m, mass = 1.00 ✕ 102 kg) is initially stationary. The disk is free to rotate in the horizontal plane about a frictionless axis perpendicular to the center of the disk. A 50.0 kg person, standing 1.75 m from the axis, begins to run on the disk in a circular path and has a tangential speed of 2.60 m/s relative to the ground. Find the resulting angular speed of the disk (in...

A flat uniform circular disk (radius = 5.44 m, mass = 320 kg) is initially stationary. The disk is free to rotate in the horizontal plane about a frictionless axis perpendicular to the center of the disk. A 66.4-kg person, standing 2.40 m from the axis, begins to run on the disk in a circular path and has a tangential speed of 2.97 m/s relative to the ground. Find the magnitude of the resulting angular speed (in rad/s) of the...
