Baseballs from straight upward with an initial speed of 64 feet a second the number of feet S above the ground after T seconds is given by the equation as equals -16 T squared +64t. when will the baseball be 48 feet above ?the ground when will he hit the ground?

\n" ); document.write( "h(t) = -16t^2 + 64t
\n" ); document.write( "==============
\n" ); document.write( "-16t^2 + 64t = 48
\n" ); document.write( "Solve for t
