You shoot an arrow straight up at 50 meters per second. When will it run out of speed?
\n" ); document.write( ":
\n" ); document.write( "Assume you mean the point when it reaches it's highest point, it stops and changes to a downward direction.
\n" ); document.write( "At that point gravity (-4.9t^2) takes over, upward velocity, is 0.
\n" ); document.write( ":
\n" ); document.write( "h = -4.9t^2 + 50t
\n" ); document.write( "the axis of symmetry of this equation gives the time of maximum height
\n" ); document.write( "t = $\"%28-50%29%2F%282%2A-4.9%29+\"$
\n" ); document.write( "t = $\"%28-50%29%2F%28-9.8%29+\"$
\n" ); document.write( "t = 5.1 seconds \n" ); document.write( "

\n" );
