Question

A ball is dropped from a treetop 256 feet above the ground. How long does it take to hit the ground? (s = 16t2)

Answer 1

4 seconds, so whatever the letter is for the answer I have provided, select it

Answer 2

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
