Answer:
The skydiver will fall 1600 ft in 10 seconds.
Step-by-step explanation:
<u>Distance a body falls from rest varies directly as the squares of the time it falls </u>
Let distance = s
time = t
Therefore , s = k 
Given, the body falls 64 ft in 2 seconds.
Substituting in above equation,
64 = k 
64 = k 
k = 
k = 16 ft/
We have to find how much he will fall in 10 seconds.
s = k 
s = 
s = 
s = 1600 ft
