A rigid body, with three different principal moments (?1,?2,?3) is rotating at t = 0 about one of its principle axes (e3).
(a) Write down Euler’s equations for the body, you can assume zero torque
(b) If ?1 = ?, ?2 = 2? and ?3 = 1/2? is the motion stable under small kicks?
(c) What about if ?1 = ?, ?2 = 1/2? and ?3 = 4? ? Justify your answers in both instances

Light from the sun reaches the earth in 8.3 minutes. the velocity is 3.00 x 10^8 m/s. how far is earth from the sun? i know how to get to d = (3 x 10^8 m/s)(498 sec). i just don't know how to get from there to the answer being 1.5 x 10^11 m.
