3. Two asteroids collide and stick together. The first asteroid has mass of 15 × 10³ k and is initially moving at 770 m/s. The second asteroid has mass of 20 × 10³ kg an is moving at 1020 m/s. Their initial velocities made an angle of 20° with respect to each other. What is the final speed and direction with respect to the velocity of th first asteroid? How much thermal energy is generated in the collision?
