Some fireworks are fired vertically into the air from the ground at an initial speed of 80 feet per second. The equation for this object’s height h at time t seconds after launch is
h= -16t^2 + 80t
How long will it take the fireworks to reach the ground?
Answers: 2
is inaccurate. It implies we're launching the ball from the height of zero feet.This will not appear to be a possibility. 
, thus we'll make our function 
Because this is a quadratic with such a missing C term, the equation is 
.
, that'swhy, the final answer is "5 seconds".
