Show your work. Your final answers should have the correct number of significant figures, units, and a box around them. 1. Two asteroids collide and stick together. The first asteroid has mass of 15 x 103 kg and is initially moving at 770 m/s. The second asteroid has mass of 20 x 103 kg 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 of the asteroids with respect to the velocity of the first asteroid after the collision
