Answer:
4
Step-by-step explanation:
Given : A ball is dropped from a treetop 256 feet above the ground.
Formula: \(s=16t^{2}\)
To Find :Time taken to hit the ground
Solution
formula given:
\(s=16t^{2}\)
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.
\(256=16t^{2}\)
⇒\(\frac{256}{16} = t^{2}\)
⇒\(16 = t^{2}\)
⇒\(\sqrt[2]{16} = t\)
⇒\(4= t\)
Thus, Total time taken to hit the ground is 4
