Answer:
4
Step-by-step explanation:
Given : A ball is dropped from a treetop 256 feet above the ground.
Formula: [tex]s=16t^{2}[/tex]
To Find :Time taken to hit the ground
Solution
formula given:
[tex]s=16t^{2}[/tex]
s denotes the total distance
t denotes the total time
Since we are given that ball is dropped from a treetop 256 feet above the ground i.e. s = 256
put value s in the formula to find value of t(total time taken to hit the ground.
[tex]256=16t^{2}[/tex]
⇒[tex]\frac{256}{16} = t^{2}[/tex]
⇒[tex]16 = t^{2}[/tex]
⇒[tex]\sqrt[2]{16} = t[/tex]
⇒[tex] 4= t [/tex]
Thus, Total time taken to hit the ground is 4
