Question 189714
General Equation: *[Tex \LARGE s=-16t^2+v_{0}t+s_{0}] ... *[Tex \LARGE v_{0}] is initial velocity and *[Tex \LARGE s_{0}]  is initial height



*[Tex \LARGE s=-16t^2+v_{0}t+s_{0}] 


"initial velocity of 40 feet per second from the top of a 30-foot building" ---> *[Tex \LARGE v_{0}=40] and *[Tex \LARGE s_{0}=30]  


Ans: *[Tex \LARGE s=-16t^2+40t+30]
