Modern Physics: Special Relativity All of these are part of one question; a) Sam once again gets on a spaceship and travels to a planet 13 ly (light years) away at a speed 0.5c while Alex stays on Earth. How long does the entire trip take in Sam’s rest frame? b) In Alex’s? c) During the return trip, Sam turns on a lamp with a wavelength of 500 nm to send a signal to Alex. What wavelength does Alex observe?

A circular rock 5 km in radius hits the earth head-on, at speed 36 km/s. The rock's density is 3 g/cm3. The earth's mass is 6*1024 kg. Treating the earth as initially stationary, calculate its final in speed due to the impact. Because of the system's trouble with small numbers, calculate the speed in μm/s -- the distance unit is the micron or micrometer, 10-6 meter. I am so confused on where to start, like is the rocks density m2...

A distant galaxy is simultaneously rotating and receding from the earth. As the drawing shows, the galactic center is receding from the earth at a relative speed of uG = 2.00 × 106 m/s. Relative to the center, the tangential speed is vT = 0.380 × 106 m/s for locations A and B, which are equidistant from the center. When the frequencies of the light coming from regions A and B are measured on earth, they are not the same...

A rocket, launched from the Earth, shuts off its engines when its speed is 4.90 km/s. It reaches a maximum altitude H of 2790 km before it falls back to Earth. At what altitude l did the rocket's engines shut off? The mass, radius, and escape speed of the Earth are 5.972 x 1024 kg, 6.371 x 106 m, and 11.18 km/s respectively (4 points)

The distance from earth to the center of the galaxy is about 22500 ly (1 ly = 1 light-year = 9.47 ? 1015 m), as measured by an earth-based observer. A spaceship is to make this journey at a speed of 0.9950c. According to a clock on board the spaceship, how long will it take to make the trip? Express your answer in years (1 yr = 3.16 ? 107 s). Please be as detailed as possible in your response,...
