**DISCUSSION and HINTS**

Since the cable does not stretch ( R_dot = 0), an observer on aircraft A will see a circular path for B, although the path of B is more complicated than that. In addition, R_ddot = 0, and since θ_dot = constant, then θ_ddot = 0.

It is recommended that you write down the relative motion kinematics equations relating the motions of A and G:

**v**_{B} = **v**_{A} + **v**_{B/A
}**a**_{B} = **a**_{A} + **a**_{B/A}

and use a set of polar coordinates to describe **v**_{B/A} and **a**_{B/A} .

Is there a solution video for this problem?

The solution video linked for this problem is the one for H.1.I, not H.1.J.

The link has now been fixed. Thanks for bringing this to our attention.
