Two asteroids collide and stick together, as indicated in the diagram. Asteroid 1 has mass m1 = 15300 kg and is initially moving in the positive x direction with speed v1 = 750 m/s. Asteroid 2 has mass m2 = 24700 kg and is initially moving with speed v2 = 1290 m/s at an angle 0 = 49.70 with the positive x axis. After the collision, the composite object moves with speed v at an angle o with the positive x axis.
