mondayfugal orbit
i don't like mondays. most people waste 1/7th of their lives on mondays. but i have a plan. a brilliant plan. you can live just east of the international date line. at 11:59:59 pm every sunday you can jump over line and poof! it's 12:00:01 am tuesday. you've completely skipped monday. well, pretty close. but hah. any fool can do that. i'm going to build a spaceship and live it. put it in a circular orbit so that it crosses the international date line every week at midnight sunday. voila! i will never have to experience another monday. ever. so here's an easy math problem for you. calculate the height of such an orbit.
