A nurse on Earth measures the resting heart rate of a patient as 76.0 beats/min. Imagine the patient travels aboard a space vessel moving with a constant speed of 0.97c with respect to the Earth. What would be the patient's resting heart rate (in beats/min) as measured by someone else aboard the vessel?
