b) A particle is travelling through the Earth’s atmosphere at a speed of 0.6c. To an Earth-bound observer, the distance it travels is 4.0 km. How far does the particle travel in its own frame of reference?
c) A particle of rest mass 2.0 kg has an initial speed of 8 210 ms-1. A constant relativistic force of magnitude 6 1.5 10 N is exerted on the particle in the same direction as the initial relativistic momentum for 1000 s. Calculate the magnitudes of the initial and final relativistic linear momentum and its final speed.
d) A star emits light with wavelength 420 nm. An observer on earth measures the wavelength of the light received from the star to be 600 nm. Calculate the speed with which the star is moving.
