#### Answer:

Velocity:

#### Explanation:

Note that it doesn't matter that

The initial distance between

The distance between

Since this is the change in position relative to each other

the relative *speed* of

The tan of the angle (relative to the horizontal/X-axis) is

Therefore the angular component of the velocity is
