hi Finace,

First you need to determine the value of the constants

$$g=? \qquad v_0=? \qquad h_0=?$$

then substitute the values into the formula and simplify it.

now you have height as a concave down parabola function in terms of time.

Now factorize the quadratic and sketch the parabola.

See how much of it you can do by yourself?

Hi Melody, I tried the question by my self and got -2(x-2)^2 +18. I got this from -1/2(4)x^2+8x+10 and after I solved that I got what I first said.

Firstly there is no x in the question.   Use the pronumerals that you are given.

I asked you for    $$g=? \qquad v_0=? \qquad h_0=?$$

You have not given them to me. But you have obviously done it.

what you have done is not exactly wrong.

Can you please present it properly though, as an equation, and with the correct letters. Then I will look at it with you.
