The function f(x) =- 16r^2 + s0, represents the approximate height (in feet) of a falling object t seconds after it is dropped from an initial height of s0, (in feet). A marble is
dropped from a height of 36ft.
A. After how many seconds does the marble hit the ground
suppose the initial height is Kay feet higher how will this affect part a -1.5 seconds, increase the length of time to reach the ground Two seconds, decrease the length of time to reach the ground 1.5 seconds decrease the length of time to reach the ground. 1.5 seconds increase the length of time to reach the ground after how many seconds does the marble hit the ground
