 Question 161504: 1) The Path of a falling object is given by the function s=-16t^2+v^o t+s^o where v^o represents the initial velocity in ft/sec and s^o represents the initial height in feet. A) If a rock is thrown upward what an initial velocity of 64 feet per second from the top of a 25-foot building, write the height (S) equation using this information. I got s=-16t^2+64t+25 B) How high is the rock after 1 second? I got s=-16*1^2+64*1+25 so s=73 The questions I need the help on is C)& D) C) After how many seconds will the graph reach maximum height?
