The formula h=-16t^2+vt gives the height h in meters of an object after t second, when it is shot upward into the air with an initial velocity v in meters per second.
\n" ); document.write( " After how many seconds will the object hit the ground if it is shot with a velocity of 19.6 meters per second?
\n" ); document.write( " When the object hits the ground the h=0, therefore
\n" ); document.write( "-16t^2 + 19.6t = 0
\n" ); document.write( "Divide by -t
\n" ); document.write( "16t - 19.6 = 0
\n" ); document.write( "16t = 19.6
\n" ); document.write( "t = 19.6/16
\n" ); document.write( "t = 1.225 sec to hit the ground
\n" ); document.write( ":
\n" ); document.write( "The h is 58.8 meters high
\n" ); document.write( "The object never gets that high as you can see
