Two asteroids with the same mass are in the connecting line between Mars and Jupiter. Asteroid A, initially moves straight (positive x-axis) with velocity 40 m / s deflected 30 ° to the direction it was coming from, when hitting Asteroid A which was initially silent. After collision Asteroid B moves in 45 ° direction towards Asteroid A. (a) Find the velocity of each asteroid after the collision. (b) What percentage of energy was lost from Asteroid A during the collision?
