A hot air balloon has just lifted off and is rising at the constant rate of 1.30 m/s. Suddenly, one of the passengers realizes she has left her camera on the ground. A friend picks it up and tosses it straight upward with an initial speed of 10.6 m/s. If the passenger is 2.70 m above her friend when the camera is tossed, how much time does it take for the camera to reach her?
