A hot-air balloon has just lifted off and is rising at the constant rate of 1.51 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 13.00 m/s. If the passenger is 2.68 m above her friend when the camera is tossed, how high is she when the camera first reaches her?
