Question

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) = –16t^2 + 25, where t is the number of seconds. For which interval of time is the acorn moving through the air?

Answer 1

The problem ask to calculate the interval of time on which the acorn is moving through the air were as the distance is calculated as the equation of S(t)= -16t^2 + 25 and the best answer, based on my calculation is 1.25 seconds. I hope you are satisfied with my answer and feel free to ask for more
