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: The 24th Amendment ended the poll tax.The 24th amendment was proposed on August 27, 1962, and passed on January 23, 1964. The congress has the power to enforce this article. Not long ago, citizens in some states had to pay a fee to vote in an election. This money was called a poll tax. The 24th amendment was important to the Civil Rights Movement as it ended mandatory poll taxes that prevented many African Americans. Poll taxes, , effectively prevented African Americans from having any sort of political power, but greatly in the South. When the 24th amendment passed, five southern states, Virginia, Alabama, Texas, Arkansas, and Mississippi still had poll taxes.
On January 23, 1964, the U.S. ratified the 24th Amendment to the Constitution, prohibiting any poll tax in elections for officials. The Congress has the power to enforce this article by appropriate legislation. If a citizen does not have enough money to pay poll tax to vote, it would be unconstitutional to not let those people vote.
