Determine what was the heart rate

Reference no: EM13553983

An astronaut with a steady heartbeat of 57 beats per minute travels at a constant speed of 0.91c, relative to earth. During the voyage his heart beats 5.2 106 times. From the earth's reference frame, how many times did the astronaut's heart beat? From the earth's reference frame, what was the heart rate?
