Problem: Calculate the velocity and acceleration from an inertial reference frame of a particle whose motion functions (in Cartesian's coordinates) are known from a moving referential. The motion of such a referential is in accelerated translation and rotation with respect to the inertial one. Identify the corresponding expression of tangential, centripetal and Coriolis's accelerations. 2. Relevant equations Galileo's transformations... hmm not sure. I don't think so since I'm dealing with a non inertial reference frame. 3. The attempt at a solution I'd like some guidance. I'm thinking of starting writing the motion of the particle the referential sees but I have a big confusion when it comes to the rotational part (is it a spin and an orbital motion?). My other idea is to start to write down a similar relation to Galilean's transformation. The translation from one frame to another involves an acceleration. I call it [tex]a(t)=\ddot f(t)[/tex], [tex]v(t)=\dot f(t)[/tex] and [tex]r(t)=f(t)[/tex]. But I've no clue about the rotational part. Also big troubles with the translational part. I'd like some guidance. Thanks.
