a) Determine an equation to represent the height of the ball relative to its horizontal distance away from its starting point(origin).

b) What is the maximum height of the ball?

**Steve**, Thursday, July 11, 2013 at 10:46amYou know that y(0) = y(35) = 0

So, y = ax(x-35)

Since y(25) = 2,

a(25)(25-35) = 2

a = -1/125

y(x) = -1/125 x(x-35)

max height is achieved at x = 35/2, so

y(35/2) = 49/20 = 2.45
