S1 [10 points]: Neutron stars are extremely dense objects that are formed from the remnants of supernova explosions. Many rotate very rapidly. Suppose that the mass of a certain spherical neutron star is twice the mass of the Sun and its radius is 10.0 km. Determine the greatest possible angular speed it can have so that the matter at the surface of the star on its equator is just held in orbit by the gravitational force. S2 [10 points]: A mass m is connected to two springs with equal spring constants k as shown in Figure below. The mass is pulled a distance a to the right and begins to oscillate. What is the period of oscillations?
