Linear Momentum [Choose Question 6 5 pts A star rotates with a period of 27 days about an axis through its center. The period is the time interval required for a point on the star's equator to make one complete revolution around the axis of rotation. After the star undergoes a supernova explosion, the stellar core, which had a radius of 12.000 km, collapses into a neutron star of radius 3.9 km. Determine the period of rotation of the neutron star. Write your answer in terms of seconds. Moment of inertia of a sphere = 0.4 M R2. 5 pts Question 7 The figure shows a uniform, horizontal beam of length = 8 m and mass = 40 kg that is hanging by two cables as shown. If a person of mass = 80 kg stands at 3.8 m from the left end, what is the tension T2 in the right side cable? Write the answer in newtons. T2 T
