Question 1039641
The equation h equals minus 16 t squared plus 58 t plus 3 models the height of a baseball after is has been hit where

h is the ending height and t is the time in seconds.
=========
{{{h(t) = -16t^2 + 58t + 3}}}
This is commonly used on Earth for units in feet and seconds.
Earth's gravitational acceleration is ~32 ft/sec/sec.
58 is the vertical speed of the ball, 58 ft/sec, when hit.
3 is the ball's height when hit by the bat.
{{{h(t) = gt^2/2 + vot + ho}}} --> {{{h(t) = -16t^2 + 58t + 3}}}
g is negative due to acceleration downward.
------------
I don't know where it was hit.
