A star has a mass of 1.74×1030 kg and is moving in a circular orbit about the center of its galaxy. The radius of the orbit is 4.0×104 light-years (1 light-year = 9.5×1015 m), and the angular speed of the star is 2.5×10−15 rad/s. (a) Determine the tangential speed of the star. (b) What is the magnitude of the net force that acts on the star to keep it moving around the center of the galaxy? (a) Number Units (b) Number Units

Two spheres are each rotating at an angular speed of 22.0 rad/s about axes that pass through their centers. Each has a radius of 0.520 m and a mass of 1.57 kg. However, as the figure shows, one is solid and the other is a thin-walled spherical shell. Suddenly, a net external torque due to friction (magnitude = 0.340 N⋅m) begins to act on each sphere and slows the motion down. How long does it take (a) the solid sphere and (b) the thin-walled sphere to come to a halt? Solid sphere Thin-walled spherical shell (a) Number Units (b) Number Units
