PPT-Problem: A rocket travels away from earth at constant speed v to planet

Q The trip takes 100 years as measured on earth but only 25 years as measured on the rocket What is v Solution The rocket measures the proper time t rocket t proper. 00 10 m s 1 gravitational constant G 6673 10 11 N m kg 2 orbital constant G M 3986 10 14 m s 2 standard gravitational acceleration g 981 m s 1 Plancks constant h 6626 10 34 J s Boltzmanns constant k 1381 10 23 J K 1 first radiation constant c 1191 10 rocket rocket Rocket M is a rugged, hi-power, very linear performance.
