A girl running at a constant speed of 1.4m/s in a straight line throw a ball directly upward at 4.7 m/s. How far will she travel before the ball drops back into her hand? Ignore air fiction.
\n" ); document.write( ":
\n" ); document.write( "First find out how long the ball will be in the air,
\n" ); document.write( "t = seconds
\n" ); document.write( "Gravitational constant: -4.9 m/sec^2
\n" ); document.write( "Upward velocity: +4.7 m/s
\n" ); document.write( ":
\n" ); document.write( "-4.9t^2 + 4.7t = 0
