What formula would I use to solve this?
During a softball game, a batter hits a ball upward from an initial height of 3 feet. The height, in feet, of the softball is given by s(t)= -16t^2+70t+3, where t is the time in seconds and t=0 Which is the closest to the time when the softball will be 50 feet above the ground?

hmm, normally i would say put s(50) and solve the equation to find t, but the way they state the question it makes me wonder if you can even solve for s(50).

anonymous · Answer

Man i'm too tired for this stuff, i obviously meant s = 50 not s(50)

anonymous · Answer

$$50=-16t^2+70t+3$$ if that possible to solve?

anonymous · Answer

oh right i misinterpret the question too, lol well, than that's your answer right there.

anonymous · Answer

What you basically do, is you take the "graph" H(x)=50 which is just a horizontal line of 50 s above the x-axis. and than try to find where the graph of your given equation would cross that line. It's the same as solving for f(x)=0 except 50 places higher, does that make sense?
