anonymous · Answer

so when I throw the ball up and it hits the ground again, what will the value of H be?

wmj259 · Answer

So you are looking at what values of t(time) make h=0.
So if you notice ax^2+bx+c

You have experience with the quadratic equation?

anonymous · Answer

Quadratic equations? More or less. I barely remember, unfortunately.

campbell_st · Answer

all you need to do is set the equation to zero and solve for t

remember h = height

so if h = 0 the ball is on the ground

so its 

$$0 = -16t(t - 4)$$

hope it helps

you will have 2 values for t

t = 0 is the initial height. 

so for the other t value
