7. assignment (inelastic 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, which was initially at rest, travels at 45.0° to the original direction of A (Fig. E8.31).

(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?
