Consider a rocket launched from Vandenberg AFB, CA (longitude=34.6 degrees) having an initial velocity of 3 km/s in the northerly direction relative to the launch site. At this instant, the acceleration of the rocket relative to the launch site is 2 km/s^2.
Determine the inertial velocity and acceleration of the rocket at the time of the launch. Consider the Greenwich Meridian to be aligned with the vernal equinox direction at the launch time and that the Earth is perfectly spherical.
