- The identical twins Speedo and Goslo join a migration from the Earth to Planet X, which is 20.0 light-years away in a reference frame in which both planets are at rest. The twins, of the same age, depart at the same time on different spacecraft. Speedo's craft travels steadily at 0.905c, Goslo's at 0.680c. Calculate the age difference between the twins after Goslo's spacecraft lands on Planet X. Which twin is the older? Goslo is older by years.How much energy is required to accelerate a golf ball of mass 0.046 kg initially at rest to a speed of 0.75c?Your 1000-m-long starship has warning lights at each end that, to you, flash simultaneously every minute. You are moving directly away from the planet Zerkon at 0.70c. To a Zerkonian, do the lights flash simultaneously? If not, which flashes first— the light at the front of your ship or the trailing one?
