Answer:
730.4 m
Explanation:
The sound waves travels with a uniform motion (=constant velocity), therefore we can calculate the distance it travels using the formula:
where
d is the distance
v is the speed of the sound wave
t is the time taken
In this problem we have:
v = 332 m/s is the speed of sound in air
t = 2.2 s is the time elapsed
Therefore, the distance between the tower and the person is
The magnitude of force on the elevator cable that would be needed to lower the cat/elevator pair is 198 Newton.
<u>Given the following data:</u>
To determine the magnitude of force on the elevator cable that would be needed to lower the cat/elevator pair, we would apply Newton's Second Law of Motion:
First of all, we would calculate the total mass of the cat/elevator pair.
Total mass = 99 kilograms
Mathematically, Newton's Second Law of Motion is given by this formula;
Substituting the given parameters into the formula, we have;
Net force = 198 Newton
