Question

Speed m/s Direction 20.1 A hot air balloon decends toward the ground with a velocity of (2.2 m/s)y^. A champagne bottle is opened to celebrate take off, expelling the cork horizontally with a velocity of (6.0 m/s)x hat relative to the balloon. When opened, the bottle is 6.2 m above the ground What is the initial velocity of the cork, as seen by an observer on the ground? What is the speed of the cork, and its initial direction of motion, as seen by the same observer? Determine the maximum height above the ground attained by the cork. The response you submitted has the wrong sign. m How long does the cork remain in the air? Your response differs from the correct answer by more than 10%. Double check your calculations. s
