These questions refer to identical spaceships that you and your friend are using. The ships are equipped with identical instruments that measure lengths and times. Your friend gets in her ship and flies past you at 86.6% of the speed of light ( = 0.866c). At this speed: √1 − v 2 c⁄ 2 =0.500 (a) If you measure your ship to be 60 meters long, you will measure your friend's moving ship to be __ meters long b) As your friend passes (going 0.866c), an interval on her ship’s clock reads 15 seconds. How long is that interval (in seconds) on your clock

dx 4x 3. In so-called "natural units" (which is just a sneaky way to let us ignore a bunch of constants), the relativistic kinetic energy of a rigid body is given by the formula 1 КЕ — т V1 – v2 where m is the rest mass of the body and v is its relative speed. Alien scientists on a space station are observing an object falling into a black hole. As the object falls, it is disintegrating, losing mass at a rate of 3 (so its mass is changing at a rate of -3). How fast is the kinetic energy of the main part of the object changing when its mass is 20, its velocity is .7, and it is accelerating at a rate of .1 (remember that acceleration is the derivative of velocity with respect to time: a = dt 1Note that this formula does not make sense when v > 1. That is because in natural units, a speed of 1 corresponds to the speed of light, and nothing with positive rest mass can go that fast.
The lifetime of a free neutron is 886 s. If a neutron moves with a speed of 2.57 ✕ 108 m/s relative to an observer in the lab, what does the observer measure the neutron's lifetime to be (in s)?
In 2030, the Australian Space Agency launches a spaceship to our nearest neighbour Alpha Centauri, approximately 4 lightyears away. According to a clock on Earth how long will the rocket take to get there if it travels at v=0.999c=299482km/s (where 'c' is the speed of light equal to 299782km/s)? About 2 years. O About 6 years. O About 4 years. Zero time.
The half‑life of a certain subatomic particle at rest is about 1.00×10−8 s. With what speed V is a beam of these particles moving if one‑half of them decay in 4.00×10−8 s as measured in the laboratory? V = ? m/s
Consider a proton that has a momentum of 1.00 kg·m/s. Part (a) Calculate the relativistic parameter γ for the proton. You will have to use a 2.998 × 108 for the speed of light to get this answer correct. Part (b) What is its speed, in meters per second? Such protons form a rare component of cosmic radiation with uncertain origins.

Tony & Yuki are working at a particle linear accelerator that is 414 meters long. A particle is moving at 0.89 c in the accelerator. What is the length of the particle accelerator in meters according to the particle? Give your answer with no decimal places please.
Two atomic clocks are synchronized. One is placed on a satellite which orbits around the earth at high speeds for a whole year. The other is placed in a lab and remains at rest with respect to the earth. You may assume both clocks can measure time accurately to many significant digits. a)Will the two clocks still be synchronized after one year? b) imagine the speed of light is much lower than its actual value. How would the results of this experiment change if the speed of light was only twice the average speed of the satellite? Explain your reasoning using a calculation.
I am currently working through a physics book (Spacetime Physics by Edwin Taylor) and I have come across this question and I don't know how to solve it: "Take the differential of this equation for g to obtain an approximate algebraic expression for Δg, the change in g, for a small change Δr in height." How do I sovle this question?
Imagine an alien spaceship and a human-controlled ship moving directly toward each other. An observer on Earth measures the both of their speeds as 0.685c with respect to the Earth. What is the speed of the alien ship with respect to the human ship? That is, what is the speed of the alien ship as measured by the pilot of the human ship? Express your answer as a fraction of the speed of light, c. |VAH/c|=
