Answer: B
Explanation:
You can use the conservation of momentum, under the assumption that no mass was lost when the collision occurred. The initial momentum of the system must equal the final momentum of the system. Our system is the region including, and only including, the satellite and the space debris. Classical momentum is defined as the product of mass and velocity:
Due to mass 1 equaling mass 2, we can factor these quantities out:
Cancel the mass term on both sides to get:
We have the initial and final velocities for everything besides the final velocity of the satellite. Plug everything in:
An object in motion stays in motion, while an object at rest will stay at rest, otherwise known as inertia. So, a rolling ball will stay in motion if it's moving, whereas if it's being held in you hand and resting, it won't!
-The group 7 elements are also known as the halogens.
They include fluorine, chlorine, bromine and iodine, which all have seven
electrons in their outer shell.
-The noble gases
make a group of chemical elements with comparable properties; under standard
conditions, they are all odorless, colorless, monatomic gases with very low
chemical reactivity. The six noble gases that occur naturally are helium, neon,
argon, krypton, xenon, and the radioactive radon. FACT: They can also act like

SI or the Systeme' Internationale' is a body in science that fixes the unit of measurements used for different basic dimensions. The SI unit for distance is meter while that of time is second. Since velocity is equal to distance over time, the SI unit for velocity is m/s.
