The distance that an object falls from rest, when air resistance is negligible, varies directly as the square of the time that i
Amiraneli [1.4K]

Answer:

\boxed{301865\:feet}

Step-by-step explanation:

Let the distance be d and the time be t.


It was given that the distance, d, varies directly as the square of the time t, we write the proportional relation,


d\propto t^2.


\Rightarrow d=k t^2, where k is the constant of variation.


It was also given that, d=193,193, when t=44.


\Rightarrow 193193=k (44^2)


\Rightarrow 193193=1936k


\Rightarrow \frac{193193}{1936}=k


\Rightarrow k=99.79


Now the equation of variation becomes;

d=99.79t^2


When, t=55s, d=99.79(55^2)


\Rightarrow d=99.79(3025)


d=301864.75

The object will travel 301865 feet in 55 seconds.

maxonik [38]
Hank is 9 years old. Explanation - What I did is I made a chart, and the categories were Sam and Hank. Then all I did was add 5 to Sam's age and added 3 to Hank's age. I repeated this until the sum of the ages equaled 24.
