8.30 Asteroid Collision. Two asteroids of equal mass in the aster- oid 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. E8.30). (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? Figure E8.30 A A 40.0 m/s 30.0° B T- 45.0°
