(a) A person's "resting" heart rate is his or her normal heart rate measured while sitting still (and long after doing anything physically exerting). A nurse on Earth measures the resting heart rate of a patient as 66.0 beats/min. Imagine the patient travels aboard a spaceship moving with a constant speed of 0.89c with respect to the Earth. What would be the patient's resting heart rate (in beats/min) as measured by someone else aboard the ship? beats/min (b) Imagine an...

24. An astronaut at rest has a heart rate of 65 beats/min. What will her heart rate be as measured by an earth observer when the astronaut's spaceship goes by the earth at a speed of 0.60 c? A. 39 beats/min B. 52 beats/min C. 108 beats/min D. 81 beats/min
An astronaut at rest on Earth has a heartbeat rate of 61 beats/min.
An astronaut at rest on Earth has a heartbeat rate of 61 beats/min. When the astronaut is traveling in a spaceship at 0.81c, what will this rate be as S measured by an observer also in the ship and an observer at rest on Earth? (a) an observer also in the ship (b) an observer at rest on Earth

A spacecraft of proper length Lo = 48.0 m is moving in the +x direction at a constant Lorentz factor y = 2.20 relative to an inertial frame, the Earth frame. The spacecraft is aligned with the direction of motion. The tip of the spacecraft crosses the origin (x = 0) at tA = 0 in the Earth frame and t'A = 0 in the frame of the moving spacecraft. a. What is the speed parameter of the spaceship B?...

An observer at rest on the Earth observes two spacecraft moving toward one another. Spacecraft 1 travels to the right at a velocity of 0.71 c relative to the observer. Spacecraft 2 travels to the left at a velocity of 0.71 c relative to the observer. What is the velocity of Spacecraft 1 relative to Spacecraft 2 (give your answer in terms of “c”)? Make sure that you draw a diagram and that you label S, S’, ux, ux’, and...
