# Suppose a star the size of our sun, but of mass 8.0 times as great, were rotating at a speed of 1.0 revolution every 12 days. if it were to undergo gravitational collapse to a neutron star of radius 12 km, losing 3/4 of its mass in the process, what would its rotation speed be? assume the star is a uniform sphere at all times.

(a) assume that the thrown-off mass carries off no angular momentum, in rev/s

(b) assume that the thrown-off mass carries off its proportional share (3/4) of the initial angular momentum, in rev/s

Ga 150 kg object is suspended below the xy-plane by a short cable attached to a steel ring located at the origin (0, 0, 0) as shown below in the figure. an object, 5 cables, 4 vectors, and a square on the x y z coordinate space. the square has its corners at (5, -5, 5), (5, 5, 5), (-5, 5, 5), and (-5, -5, 5). 4 of the cables connect the corners of the square to the origin. the fifth cable extends from where the other 4 meet down to the 150 kg object. the four vectors all begin at the origin and extend up along one of the cables. the vector on the cable connecting the origin to (5, -5, 5) is labeled t_1. the vector on the cable connecting the origin to (5, 5, 5) is labeled t_2. the vector on the cable connecting the origin to (-5, 5, 5) is labeled t_3. the vector on the cable connecting the origin to (-5, -5, 5) is labeled t_4. 150 kg the ring itself is attached to 4 ropes which are attached to the ceiling, which is 5 meters above and parallel to the xy-plane. the ropes are attached to the ceiling at the points (â’5, â’5, 5), (5, â’5, 5), (5, 5, 5), and (â’5, 5, 5). use symmetry to find the exact magnitudes t1, t2, t3, and t4 of the tensions in the cables, and use g
