Two asteroids of equal mass collide with a glancing blow. Asteroid A, which was originally 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 initial direction of A.
(a) Find the speed of each asteroid after the collision.
(b) What fraction of the original kinetic energy of asteroid A dissipates in the collision?
