Answer:
The collision occurs at a height of 1/3 of the total height of cliff.
Explanation:
The situation is represented in the attached figure:
For the stone dropped from top of cliff we have
Initial velocity of drop= 0 m/s.
Now the time at which it attains a velocity of 2v is obtained from first equation of kinematics as
Thus the distance it covers in this time can be calculated using third equation of kinematics as
For the stone thrown upwards the velocity at collision is give as 'v' thus the velocity at which it is thrown upwards can be calculated by first equation of kinematics as
The height over which it changes it's velocity from '3v' to 'v' can be again obtained from third equation of kinematics as
Thus the collision occurs at at a fraction of 1/3 of height.
Answer:
I will answer these personally haha, I had the same assignment :)
Explanation:
1. Single use plastics, polluting the ocean are a part of or daily life, and is messing up our oceans. In 100 years, if we make an effort to clean the oceans, we can advance pollution control.
2. Confrontation with fear itself. "The only thing to fear is fear itself". I would rather die than be paranoid over nothing.
3. Because either the person is forced abusively by the significant other, or they are forced upon by a problem, such as pregnancy, or economic issues.
4. Lack of use in certain organs. Humans can live without having certain organs such as an appendix, and etc. In the past, we needed these to survive in a world where an organism's fitness isn't compromised.
5. No. In my opinion, based on how the world is going, I feel like humans won't be able to evolve into something else. I believe that we will be extinct before we can because the world is focused on war, economy, etc., rather than the health of our own planet, which we need in order to survive.
6. I feel like the family surrounding the eldery or members of government should take care of them. Family comes first, not personal benefit.
Third, the people wanted their sins to be forgiven, to go to heaven or to take back goods from the Holy Lands or because they had committed a crime and were forced by the church to go on a Crusade. And some people just went on Crusades for fun. Taking back Jerusalem was the main reason why Crusades occurred.
Fines is the administrative penalty can be imposed against a retail licensee that knowingly permitted the illegal sale, or negotiations for the sales, of controlled substances.
