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.
