UNAAB: Physics geniuses, come and cry//// Decepticons are actually constructing a large space fighterjet whose intention is to destroy the planet EARTH, greenberg and schroodinger are 20 and 15 years old respectively, schroodinger constructed a jet bullet dat is relatively designed to destroy the decepticons jet upon collision, but has to be operated by someone, assuming greenberg drove the bullet directly from the earth to hit the stationary decepticons jet in space which is 9.5 x 10^16 metres away from the earth, how many years does it take the greenberg to get there if his rocket bullet is travelling at a speed of 1.5 x 10^8 metre per seconds, if the jet takes a sharp u turn and head back to the the earth with the same speed, and landed safely(assuming no damage is'nt induced), how old will greenberg appear to be? Who is now older in greenberg and schroodinger.......(All sort of answers are welcomed......enjoy!!)?
