Best ResponseYou've already chosen the best response.0hint: \(\bf \text{initial velocity}\\ h = 16t^2+v_ot+h_o \qquad \text{in feet}\\ h = 4.9t^2+v_ot+h_o \qquad \text{in meters} \\ \quad \\ v_o=\textit{initial velocity of the object}\\ h_o=\textit{initial height of the object}\\ h=\textit{height of the object at "t" seconds}\)
