Scientists observe an approaching asteroid that is on a collision course with Earth. They devise a plan to launch a rocket that will collide with the asteroid inelastically and stop it. The mass of the asteroid is 7500 kg, and it is approaching Earth at 85 m/s. If the rocket has a mass of 900 kg, approximately what velocity must it have to completely stop the asteroid after collision?

A. 151 m/s
B. 305 m/s
C. -708 m/s
D. 68 m/s

Answer :

Answer:

I would have to be A

Explanation:

negative numbers wouldn't work here and 68 wouldn't be fast enough to stop it because the asteroid is much heavier than the rocket
