Disregarding wind resistance the distance a body falls from rest varies directly as th squares of the time it falls if a skydiver falls 64ft in 2 seconds, how far will he fall in 10 seconds

Respuesta :

Answer:

The skydiver will fall 1600 ft in 10 seconds.

Step-by-step explanation:

Distance a body falls from rest varies directly as the squares of the time it falls

Let distance = s    

      time = t

Therefore , s = k [tex] \times t^{2}[/tex]

Given, the body falls 64 ft in 2 seconds.

Substituting in above equation,

64 = k [tex] \times (2)^{2}[/tex]

64 = k [tex] \times (4) [/tex]

 k  = [tex]\frac{64}{4}[/tex]

 k = 16 ft/[tex]s^{2}[/tex]

We have to find how much he will fall in 10 seconds.

s = k [tex] \times t^{2}[/tex]

s = [tex]16 \times 10^{2}[/tex]

s = [tex]16 \times 100[/tex]

s = 1600 ft
