\n" ); document.write( "(Note that s(t) is just function notation for the height of the ball and NOT s
\n" ); document.write( "multiplied by t; also note where the initial height and initial velocity values play a role in the equation.
\n" ); document.write( "How many seconds will it take for the ball to return to the surface? Round answer to the nearest hundredth. Don’t forget units!! \n" ); document.write( "
