In American football, the ball is punted by dropping and kicking it before it hits the ground.
The height h(t) of the football above the ground in meterst
seconds after being punted is affected by gravity and by the punter's kick,
and can be represented as the difference of two functions: a (t) 4.91",
which specifies the effect of gravity on the height of the ball, and v (t) 12.12 +2.5, which specifies the effect of the punt on the ba
With these two functions, h(t) == v(t) a(t), how high above the ground was the ball when it was punted?
