The rod OB rotates counterclockwise about O (Polar Coord.)

[Alexanddros81]

Homework Statement

13.25 The rod OB rotates counterclockwise about O at the constant angular speed
of 45 rev/min while the collar A slides toward B with the constant speed 0.6 m/s,
measured relative to the rod. When collar A is in the position R = 0.24m, θ = 0, calculate
(a) its velocity vector; and (b) its acceleration vector.

When collar A is in the position R = 0.24m, θ = 0, calculate
(a) its velocity vector; and (b) its acceleration vector.

With respect to an inertial or a rotating coordinate system?
