Question 324951
The path of a ball projected in the air can be represented by the equation h=16t^2+64t where h represents height, and t represents time at what time is the ball 48 feet high?
-------------------------------
h=16t^2+64t
Set h = 48
{{{16t^2 + 64t = 48}}}
{{{t^2 + 4t - 3 = 0}}}

{{{t = -2 + sqrt(7)}}} no units given
I don't think your equation is right.  The ball never comes back down.
