Answer:
17.82J
Explanation:
Kinetic energy = 1/2 mv^2
Given
Mass M = 0.45kg
Velocity v = 8.9m/s
Therefore,
K.E. = 1/2 x 0.45 x (8.9)^2
= 1/2 x 0.45 x (8.9 x 8.9)
= 1/2 x 0.45 x 79.21
Multiply through
= 35.6445/2
= 17.82J
The kinetic energy of the ball is 17.82J

Answer:
The diameter is 0.000056 m
Explanation:
Lets explain the relation between the meter and the micrometer
1 Meter is equal to 1000000 (one million) micrometers
1 micrometer = ![\frac{1}{1000000}=\frac{1}{10^{6}}=10^{-6}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B1000000%7D%3D%5Cfrac%7B1%7D%7B10%5E%7B6%7D%7D%3D10%5E%7B-6%7D)
The symbol of the meter is m
The symbol of micrometer is μm
A human hair is approximately 56 µm in diameter
We need to express this diameter in meter
To do that we divide this number by 1,000,000 or multiply it by ![10^{-6}](https://tex.z-dn.net/?f=10%5E%7B-6%7D)
→
56 µm = 0.000056 m
→ OR
→
→ 56 µm = 0.000056 m
<em>The diameter is 0.000056 m</em>
