Question:

Asteroid Collision Two asteroids of equal mass in the asteroid belt between Mars and Jupiter collide with a glancing blow. Asteroid A, which was initially traveling at 40.0 m/s, is deflected 30.0" from its original direction, while asteroid B travels at 45.0 to the original direction of A (Fig. 8.36).
(a) Find the speed of each asteroid after the collision.
(b) What fraction of the original kinetic energy of asteroid A dissipates during this collision?
