A simple random sample is a sample drawn in such a way that <em>each member of the population has equal chance for being included in the sample</em>.
The speed of the ball just before impact was v=√(2gh) = 6.26m/s. The acceleration is twice this over the time (twice because the second speed is the same in the other direction, meaning the total change in speed is 2V)
a = 12.52/0.10 = 125.2m/s²
The force is F=ma, so F = 0.5kg·125.2m/s² = 62.6N

50 μm = 5 × 10⁻⁵ m in diameter
<h3>Steps</h3>
1μm = 1 x
m
<h3>Given</h3>
1μm = 1 x
m
50μm = 50 x
m
50μm = 50 x 10 x 
50μm = 5 x
m
<h3>Conclusion</h3>
A human hair is approximately 50 μm = 5 × 10⁻⁵ m in diameter
<h3>How big is a human hair on average?</h3>
between 17 and 181 micrometers
The typical diameter of human hair can range from 17 micrometers to 181 micrometers, according to research. Using 50 micrometers as an average figure for its diameter, this translates to 50,000 nanometers.
<h3>What is a human hair's diameter in inches?</h3>
The finest hair is flaxen, with a diameter ranging from 1/1500 to 1/500 of an inch. the coarsest hair is black, measuring between 1/450 and 1/140 of an inch.
