Question

Neglecting air​ resistance, the distance s(t) in feet traveled by a freely falling object is given by the function s(t) = 16t^2 where is time in seconds. The height of a certain tower is 878 feet. How long would it take an object to fall to the ground from the top of the​ building?

Answer 1

7.4 seconds

Explanation:

878 = 16 t^2 divide both sides of the equation by 16

54.875 = t^2 take positive sq rt

7.4 seconds
