Answer:
Ratio is 7.58
Explanation:
At the bottom of the circle, the net force is given by
where m is mass of plane, v is the speed of plane, r is vertical circle radius
Since W=mg, dividing left side by W and right side by mg we obtain
=7.578096
=7.58
Considering that =7.58 which is greater than 2, the pilot is advised to wear the anti-G suit
Answer:
Lc = 242 [m]
Explanation:
The circumference is defined as the circumference length of a circle, this length can be calculated by means of the following equation.
where:
Lc = circumference length = 220 [m]
r = radius [m]
Now we can clear r
Now we can determine the outer radius with the inner diameter plus the width of the track.
R = r + 3.5
R = 35.01 + 3.5 = 38.51 [m]
The outer circumference is:
You apparently skipped some words and didn't copy them into the question. Fortunately, those words were part of the "red herring" section ... the part that only distracts you, and is completely unnecessary in order to answer the question.
The actual question here is: "What fraction of an hour is 7.2 seconds ?"
(7.2 sec) x (1 hour/3,600 sec) = 7.2 / 3600 = <em>0.002 hour </em>.
