A golf ball is dropped from rest from a height of 9.5m.  It hits the pavement then bounces back up rising  just 5.7 m before falling back down again.  A boy then catches the ball on the way down when it is 1.20 m above the pavement.  Ignoring air resistance, calculate the total amount of time the ball is in the air, from drop to catch.
