a stone with a mass of 0.100 kg rests on a frictionless, horizontal surface. a bullet of mass 2.40 g traveling horizontally at 525 m/s strikes the stone and rebounds horizontally at right angles to its original direction with a speed of 315 m/s .a stone with a mass of 0.100 kg rests on a frictionless, horizontal surface. a bullet of mass 2.40 g traveling horizontally at 525 m/s strikes the stone and rebounds horizontally at right angles to its original direction with a speed of 315 m/s . a) compute the magnitude of the velocity of the stone after it is struck.
b) compute the direction of the velocity of the stone after it is struck. (degrees from the initial direction of the bullet)

The “death throes” of stars are amongst the most complex phenomena in all of astronomy, and the “corpses” of stars amongst the most energetic and exotic objects in existence. beginning at the end of the core helium fusion stage in a star’s life, describe in detail the post-main sequence development of both (a) a 1.0 solar mass star, and (b) a 25.0 solar mass star. in what significant ways do they differ? what role does each of these types of stars play in the "star-gas-star" cycle and the evolution of chemical elements in our galaxy?
