Need help with principle of relativity

  1. I am sorry if it is wrong topic , and sorry if it is a bit bad text - translated it from estonian to english. If someone could do it and maybe explain this- that would be great.

    1. The problem statement, all variables and given/known data

    1)In the reference system K is point M with coordinates x=5m , y=2m and z=8m. You have to find that point coordinates in refenrece system K', which moves with velocity 7 m/s aiming z-axis.

    2)Particles equations of motion in reference system K' is
    x'=5t+4
    y'=0
    z'=0

    Write out this particles equations of motion in reference system K, if:

    a) K' is still according to K and its deperature point coordinates are O' (2;0;0).

    b) K' is moving according to K evenly and straight with velocity 10 m/s aiming x-axis.
    On observation start-moment t=0 both coordinate systems deperature points were same.

    2. Relevant equations
    Galilei's principle of relativity, Galilean transformation and and inertial reference frame.

    Hi latel, welcome to PF!:smile:

    We don't do your homework for you here; you need to make an attempt and show your work, so that we can see where you are having trouble.
     
  4. I cant understand this - how to put these in to coordinate system ?
