6. A star of mass 1.4M SuN (is the Sun's mass, a convenient mass unit in Astronomy) is a great distance from another star of equal mass and is approaching the second star at v 680km /s. The two stars undergo a close encounter (considered a collision) and much later the first star is moving at a θ-350 to its initial direction. In the frame of reference in which the second star is initially at rest v2, 0, find the...

The mass of a star is 1.770×1031 kg and it performs one rotation in 21.90 days. Find its new period (in days) if the diameter suddenly shrinks to 0.590 times its present size. Assume a uniform mass distribution before and after. A figure skater is spinning with an initial angular speed of 9.8rad/s. He then pulls his arms in, reducing his moment of inertia to 0.27 times its original value. What is his angular speed after pulling in his arms?...
