Answer: Your question is missing below is the question
Question : What is the no-friction needed speed (in m/s ) for these turns?
answer:
20.1 m/s
Explanation:
2.5 mile track
number of turns = 4
length of each turn = 0.25 mile
banked at 9 12'
<u>Determine the no-friction needed speed </u>
First step : calculate the value of R
2πR / 4 = πR / 2
note : πR / 2 = 0.25 mile
∴ R = ( 0.25 * 2 ) / π
= 0.159 mile ≈ 256 m
Finally no-friction needed speed
tan θ = v^2 / gR
∴ v^2 = gR * tan θ
v = √9.81 * 256 * tan(9.2°) = 20.1 m/s
It is a question that leads us to know the proportion of one element to another. We have initially that the mass of the earth is of
m_E = 5.98*10^{24}kg
While the mass of the Moon is of
m_M = 7.35*10^{22}kg
The ratio between the two is given by the function
This means that the mass of the earth is 81.36 times larger than that of the Moon.
