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?

Conservation of Energy

In physics, the rule of the conservation of energy states that energy doesn’t disappear from the atmosphere; instead, it changes its form from one type to another. Energy is one of the most important physical quantities in nature, and it cannot be created or destroyed — only transformed.
