You are in a hot air balloon (yes, another balloon problem!) rising from the ground at a constant velocity of 2.70 m/s upward. To celebrate the takeoff, you open a bottle of champagne, expelling the cork with a horizontal velocity of 4.00 m/s relative to the balloon. When opened, the bottle is 4.90 m above the ground.

How long does the cork remain in the air?
