Imagine you are calculating the effects of a satellite impact on an asteroid. The satellite has a mass of 600 kg and an initial velocity of 6000 m/s. The asteroid has a mass of 5 x 10⁹ kg and is not moving. The satellite hits the asteroid and sticks to its surface. Using your equation from Lab 6b for inelastic collisions, what is the final velocity of the two objects?

Group of answer choices

3.6 x 10^(-6) m/s

7.2 x 10^(-4) m/s

1.8 km/s

72 m/s
