<PRE><B>Question 700057</B>
A rock is thrown downwards at a rate of 144 feet per second from an initial height of 352.
 Write the quadratic function that represents this vertical motion. Graph the quadratic equation on the coordinate plane provided.
:
y = -16t^2 - 144t + 352
y = height in ft
t = time in sec
:
Plot this equation from 0 to 2 seconds
 x | y
-------
 0 |352; initial height
.5 |276
1.0|192
1.5|100
2.0| 0; strikes the ground
