Question 1071642
.
- The distance, s, that an object falls is directly proportional to the square of the time, t , of the fall. 
If an object falls 16 feet in 1​ second, how far will it fall in 2 ​seconds?

- How long will it take an object to fall 400 feet?

- direct variation = {{{y=kx^n}}} where the first step is to find the constant, and I'm unsure of how to set it up!

<pre>
1.  If an object falls 16 feet in 1&#8203; second, how far will it fall in 2 &#8203;seconds?  --->  {{{16*2^2}}} = 16*4 = 64 feet.


2.  - How long will it take an object to fall 400 feet?  --->  t = {{{sqrt(400/16)}}} = {{{sqrt(25)}}} = 5 seconds.
