Explanation:
v=0, u=40m/s, S=20cm =0.2m, mass = 0.15kg.
by the formula,
v²-u²=-2aS
0-1600=-20×0.2×a
-1600/(-2×0.2) = a
4000m/s²=a
Force = mass × acceleration.
F=ma = 0.15×4000 = 600N.

a 15.8 g sample contains 3.6 g of f, 4.9 g of h, and 7.3 g of c. what is the percent composition of fluorine in this sample?
The percentage mass of Fluorine in the sample can be calculated using the ratio formula. Hence, the percentage composition of Fluorine is 22.78%
Total grams of sample = 15.8 grams Mass of Fluorine = 3.6 grams Mass of hydrogen = 4.9 grams Mass of carbon = 7.3 gramsThe percentage composition of Fluorine can be written thus :
(Mass of Fluorine ÷ total mass) × 100%Percentage composition = (3.6÷15.8) × 100%
Percentage composition = 0.2278 × 100% = 22.78%
Therefore, the percentage composition of Fluorine is 22.78%

Taking into account the definition od percentage composition, the percent composition of fluorine in this sample is 22.78%.
The Percentage Composition is a measure of the amount of mass that an element occupies in a compound and indicates the percentage by mass of each element that is part of a compound.
To calculate the percentage of composition, it is necessary to know the mass of the element in a known mass of the compound.
In this case, you know that a 15.8 g sample contains 3.6 g of F, 4.9 g of H, and 7.3 g of C.
Dividing the mass amount of F present in the compound by the mass of the sample and multiplying it by 100 to obtain a percentage value, the percentage composition of fluorine is obtained:
[tex]percentage composition of fluorine=\frac{3.6 grams}{15.8 grams} x100[/tex]
percentage composition of fluorine= 22.78%
Finally, the percent composition of fluorine in this sample is 22.78%.

the coordinates of the vertices of △abc are a(−1, 1), b(−2, 3), and c(−5, 1). the coordinates of the vertices of △a′b′c′ are a′(−1, −4), b′(−2, −6), and c′(−5, −4). which statement correctly describes the relationship between △abc and △a′b′c′?
Answer:△ABC is congruent to △A′B′C′ because you can map △ABC to △A′B′C′ using a reflection across the x-axis followed by a translation 3 units down, which is a sequence of rigid motions.
