After how much time will it take for the volleyball to hit the ground? \n" ); document.write( "--------- \n" ); document.write( "y is the height of the ball at time = t seconds. \n" ); document.write( "------ \n" ); document.write( "Height is zero when ball hits the ground: \n" ); document.write( "-------- \n" ); document.write( "-16t^2+31t+2 = 0 \n" ); document.write( "---- \n" ); document.write( "t = [-31 +- sqrt(31^2-4*-16*2)]/(-32) \n" ); document.write( "---------------------------------------- \n" ); document.write( "Find the Positive solution. \n" ); document.write( "===================== \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( "=================== \n" ); document.write( " |
