Answer:
Gravitational potential energy to kinetic energy
Explanation:
In this case you have a case about conservation of energy.
When the mass is released and allowed to fall, its energy is completely gravitational potential energy with a value of U = mgh. m is the mass, g is the gravitational constant and h is the height to the floor from the mass.
While the mass is falling down part of its potential energy converts to kinetic energy of value K=1/2mv^2, because the mass has been acquiring more and more velocity.
Thus, the kinetic energy is increasing while the potential energy is decreasing.
When the mass is just above the floor (the moment just before the mass hits the floor) all its potential energy has been converted to kinetic energy.
Then, you have that the kinetic energy of the mass when the mass is just above the floor, is equal to the potential energy when the mass is at height of h. That is:

This is how the law of conservation of energy is fulfilled.
Neither are Strong acid.
<h3>What does “strong acid” mean?</h3>
In the solution, solid acids entirely separate into ions. For instance, hydrochloric acid is a solid acid.
It totally ionizes, forming hydrogen and chloride ions. Nitric acid and sulfuric acid are also components of strong acids.
A solid or strong acid is one that has completely dissociated into ions. It is a weak acid if it does not dissociate completely.
<h3>What is an example of a strong acid?</h3>
Chloric acid, hydrobromic acid, hydrochloric acid, hydroiodic acid, nitric acid, perchloric acid, and sulfuric acid are the seven major acids that make up strong acids. These are referred to as strong acids since they can totally dissociate in water.

Take it one step at a time.
-- Remember that 'speed' means (distance) divided by (time),
and the direction doesn't matter.
-- Remember that 'velocity' means the speed and the direction.
<em>First car:</em>
360 meters east in 15 sec.
Speed = 360/15 = 24 meters per second
Velocity = 24 meters per second east
<em>Second car:</em>
120 meters west in 5 seconds
Speed = 120/5 = 24 meters per second
Velocity = 24 meters per second west
-- Their speeds (24 and 24) are equal.
-- Their velocities are equal magnitude but opposite (24 east / 24 west).

let me know if I'm right~! =^-^= hope it helps~!
