Two asteroids collide and stick together. The first asteroid has mass of 15×103kg15×103kg and is initially moving at 770 m/s. The second asteroid has mass of 20×103kg20×103kg and 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 the first asteroid?
