Answer
$x = 82.69295063~t$
$y = -16~t^2+30.09777261~t$
We can see the graph below:
Work Step by Step
$x = 82.69295063~t$
$y = -16~t^2+30.09777261~t$
When t = 0:
$x = 82.69295063~(0) = 0$
$y = -16~(0)^2+30.09777261~(0) = 0$
When t = 0.5:
$x = 82.69295063~(0.5) = 41.346475315$
$y = -16~(0.5)^2+30.09777261~(0.5) = 11.048886305$
When t = 1:
$x = 82.69295063~(1) = 82.69295063$
$y = -16~(1)^2+30.09777261~(1) = 14.09777261$
When t = 1.5:
$x = 82.69295063~(1.5) = 124.039425945$
$y = -16~(1.5)^2+30.09777261~(1.5) = 9.146658915$
When t = 1.8:
$x = 82.69295063~(1.8) = 148.847311134$
$y = -16~(1.8)^2+30.09777261~(1.8) = 2.335990698$
We can see the graph below:
