Which of the following demonstrates a translation? question 2 options: a). a spinning wheel b). a child swinging on a swing c). the blade of a kitchen blender d). a sliding hockey puck

A translation means moving something up down or left/right

Lets use that definition to figure the answer out

A). A spinning Wheel

No, because it is spinning, not moving up or down left/right

B). a child swinging on a swing

No because the child is in a swinging state of motion, not left or right, or up or down.

C). The blade of a kitchen blender

No, because it is in a spinning motion, which we ruled out to be incorrect previously.

Therefore the correct choice is

D) A sliding hockey puck

Why?

A sliding puck is always moving left or right, view the hockey field as an XY plane, and it is being translated left & right.
