The statement that describes the change in energy as one slide from the top is the decrease in the gravitational potential energy is equal to the increase in kinetic energy.
<h3>What is Kinetic energy?</h3>
This is known to be a kind of energy that is seen in an object or a particle due to its motion.
Based on the above scenario, As the block goes or slides down, its potential energy is known to lower or decreases and its velocity is said to increases and therefore, it's kinetic energy is increasing.
See options below
O The decrease in the gravitational potential energy is equal to the increase in kinetic energy.
O The sum of the kinetic energy and the gravitational potential energy changes by an amount equal to the energy dissipated by friction.
The gravitational potential energy and the kinetic energy must both decrease.
The gravitational potential energy decreases, and the kinetic energy is constant.

The 45th percentile of the data given above (P₄₅) is 16.225.
<h3>What is percentile in statistics?</h3>
Percentile refers to the mathematical or statistical term that is used to indicate the position of a data in relation to others from the sample given.
<h3>How did we arrive at the above figure?</h3>
Step 1 - First all data must be arranged in ascending order:
See the attached table for this.
Step 2 - We compute the position or rank of the 45th percentile.
The formula for percentile position is given as:
((n +1 ) *P)/100
= ((25+1) * 45)/100
= 11.70
Step 3 - Deploy the interpolation method because the position above is not an integer.
The numbers in positions 11 and 12 are where you'll find the 45 percent percentile. Based on the data arranged in ascending order, the values are 15 and 16.75.
The percentile we're seeking for is situated at the value of 11.7 - 11 = 0.7, which is the percentage of the space between 15 and 16.75.
Therefore,
(P₄₅) = 15 + 0.7 x (16.75 - 15)
(P₄₅) =16.225.
