An acorn falls from the branch of a tree to the ground 25 feet below. the distance, s, that the acorn is from the ground as it falls is represented by the equation s(t) = –16t2 + 25, where t is the number of seconds. for which interval of time is the acorn moving through the air?

a.0
b.0
c. t> 5/4

d.-5/4

or

Step-by-step explanation:

An acorn falls from the branch of a tree to the ground 25 feet below.

The distance, S, that the acorn is from the ground as it falls is represented by the equation

Where, t is number of seconds.

We need to find the time for which acorn moving through the air.

If acorn in air then S(t)>0

Taking square root both sides

Interval of t,

Hence, t is less than 5/4 and greater than 0.
