I THINK v = 9.8 is the final velocity on impact. Hope I helped
Answer:
B) The mass of the reactants equals the mass of the products.
Explanation:
In any balanced chemical reaction, it is known by default that the mass of the products and reactants must always be the same.
This is according to the law of conservation of mass.
- Every chemical reactions obey the law of conservation of mass.
- The law states that "In every chemical reaction, matter is neither created nor destroyed but changed from one form to another".
- In essence, there is no mass loss in a chemical reaction.
- This law is usually shown by the balancing of chemical species on both sides of the equation.

We can use Newton's second law to find out. This says F=ma, where m is the mass we seek:
So we see the mass is 3kg
The force involved in the orbiting of the earth is gravity!
