Question 1135263: Use the position equation s=-16t^2+VoT+So , where s represents the height of an object (in feet), Vo represents the inital velocity of the object(in feet per second), So represents the initial height of the object(in feet), anf T represents the time(in seconds). A projectile is fired straight upward from ground level (So=0)with a initial velocity of 224 feet per second.
a). At what instant will it be back at ground level?
b). When will the height exceed 768 feet.
