Question 729962: For this problem/situation: "From ground level, an objec travels upward with an initial velocity of 240 ft/sec. The height, h, in feet of the object at any given time (t) in seconds is h(t)=240t-16t (squared). Find the value of t when h(t)=0" , what would you be looking for in order to solve it? A root/solution/etc, vertex, etc.?

You have your equation for height as a function of time, h%28t%29=-16t%5E2%2B240t. You are asked exactly, find t for +h%28t%29=0. This question on that equation is clear. -16t%5E2%2B240=0, so find t. What kind of equation is that? Do you remember a general method to find a solution?
