solve using the quadratic formula H(t)= -16t+25+0
does it really say \(+0\) ??
this is first order, so i would use the quadratic formula myself....
i think something is missing from this question it is not a quadratic as it is written, also it has a \(+0\) at the end also it is not an equation, so there is nothing to solve
@kiamonstaa i think maybe you could repost the problem. i doubt this is the question exactly as it is written
this is the whole thing
Jules kicks a soccer ball off the ground and into the air with an initial velocity of 25 feet per second. Assume the starting height of the ball is 0 feet. Approximately, how long does it take until the soccer ball hits the ground again? 0.6 sec 0.8 sec 1.6 secs 2.8 secs
\[\Large s= f(t)=s_0+v_0t+\frac{1}{2} at^2\] where \( a=-g\) and \(s_0=0\) and \(s=0\)
