A spaceship (rest mass of 2500 kg) is moving close to a stationary lab somewhere in space. The people in the lab measure that it takes the spaceship 4 us (microseconds) to pass a measuring device (observer) installed in the lab and that the spaceship has a length of 600 m. (c = 3.0 x 10 m/s) (a) Find the length of the spaceship measured on earth before launch. Explain if this measurement is proper or not. (b) Find how long it takes for the spaceship to pass in front of the measuring device, measured by the astronauts inside the spaceship. Explain if this measurement is "proper' or not. (c) As the spaceship approaches the lab, a spaceship antenna emits a radio wave towards the lab; find the speed of the radio wave detected by the people in the lab.
