Answer:
1.72m
Explanation:
Step 1:
Data obtained from the question.
Displacement (x) = 0.15 m
Spring constant (K) = 300 N/m
Mass (m) = 0.2 kg
Height (h) =?
Step 2:
Determination of the energy in the spring.
The energy is a spring can be obtained by the following equation:
E = 1/2 kx^2
E = 1/2 x 300 x 0.15^2
E = 150 x 0.0225
E = 3.375J
Step 3:
Determination of the maximum height.
At maximum height, the energy stored is the spring is equal to the potential energy i.e
Energy stored in the string = potential energy
E = P.E
Recall:
Potential energy = mgh
Where:
m is the mass = 0.2kg
g is the acceleration due to gravity = 9.8m/s2
h is the height. =?
Potential energy (P.E) = 3.375J
PE = mgh
3.375 = 0.2 x 9.8 x h
Divide both side by 0.2 x 9.8
h = 3.375/ (0.2 x 9.8)
h = 1.72m
Therefore, the maximum height of the box is 1.72m

Answer:
10 hours
Explanation:
If the plane flies at 500 miles per hour, it flies 500 miles every hour. So, to find out how many hours it will take to fly 5000, you simply do 5000/500.
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 = 
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 
→ 
56 µm = 0.000056 m
→ OR
→ 
→ 56 µm = 0.000056 m
<em>The diameter is 0.000056 m</em>
