How Does Galilean Transformation Apply to Moving Coordinate Systems?

[latel]

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.

Homework Statement

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.

Homework Equations

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

Hi latel, welcome to PF!

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.

I can't understand this - how to put these into coordinate system ?
