Question 121078
The time in seconds that it takes for an object to fall from
rest is given by t=1/4 (radical)s, in which s is the distance fallen.
: 
This formula can be written:
 t = {{{(1/4)sqrt(s)}}}
:
Find the time required for an object to fall to the ground from a building that is 800 ft high.
:
Substitute 800 for s in the above formula:
t = {{{(1/4)sqrt(800)}}}
 t = {{{(1/4)28.28427}}}; found the square root of 800
 t = 7.071 seconds to fall 800 ft
:
:
 Find the time required for an object to fall to the ground from a building that is 1400 ft high. (Use the formula found in above problem)
:
Substitute 1400 for s
t = {{{(1/4)sqrt(1400)}}}
 t = {{{(1/4)37.41657}}}
 t = 9.354 seconds to fall 1400 ft
