Question 152047
You are given the equation
{{{h = -16t^2 + v[0]t + s[0]}}} 
You are told the initial velocity is 10 feet/sec so {{{v[0] = 10}}}
You are told the initial position is 8 feet above the grouns. so {{{s[0] = 10}}}

Substitute that info into the equation to get
{{{h = -16t^2 + 10t + 8 }}}

Plug in values for t from 0.1 through 1.5 and solve for h. You'll need to grind that out by hand., Just pick a few values for t and solve for h using the eqaution we just made.

graph the equation
{{{graph(400,400, -1,3, -1, 11, -16x^2 +10x +8)}}}
height is the y axis, time is the x axis.


To find the max height, look at the plot. Mark that point and then drop down to find the time and across to find the height



To find when it hits the round, set h = 0 and solve for t. Or look at the plot and find the time when the graph touches the x axis
