A quarter is dropped from rest from the fifth floor of a very tall
building. The speed of the quarter is v just before striking the ground.
From what floor would the quarter have to be dropped from rest for
the speed just before striking the ground to be approximately 2v?
Assume equally spaced floors and ignore all air resistance effects to
determine your answer.

please focus on showing the process to achieve the answer, thank you

A rock is dropped from the top of a tall tower. Half a second later another rock, twice as massive as the first, is dropped. Ignoring air resistance, they strike the ground with the same kinetic energy they strike the ground more than half a second apart. the distance between the rocks increases while both are falling. the acceleration is greater for the more massive rock.

A ball, dropped onto a hard floor from a height of 2 meters, bounces to a height of 1.8 meters, 90% of the initial height. Each subsequent bounce is 90% the height of the previous one. Find the total distance the ball travels up and down (i.e. after the first collision with the ground it has traveled 2 meters down and 1.8 meters up, giving a total distance of 3.8 meters).

2) A ball is dropped from rest at the top of a high cliff. It takes 10.00 seconds for the ball to reach the ground below. Find: a) the height of the cliff, b) the velocity of the ball hitting the ground below, c) the time it takes for the ball to fall half of the cliff's height, and d) the velocity at this halfway point. (Remember acceleration due to gravity is -9.800 m/s^2).
