Two students are tossing around frisbees designed to whistle while they are airborne. The first student flings the frisbee towards the second student at a speed of 8.1 meters per second. If the frisbee emits a frequency of 554 Hz, what frequency (in Hz) is heard by the second student? You may take the speed of sound in air to be 343 m/s. Type in your answer correct to one decimal place. Use a period for the decimal point. eg. 500.5 - do not use a comma or input your answer in some form of scientific notation. Do not include units in your answer. Type vour answer
