A golf ball is dropped from rest from a height of 9.50m. It hits the pavement, then bounces back up, rising just 5.70m before falling back down again. A boy then catches the ball on the way down when it is 1.20m above the pavement. Ignoring air resistance, calculate the total amount of time that the ball is in the air, from drop to catch.
