but by definition something that's moving isn't at rest and something that's at rest isn't moving. (i get your point, it comes to rest but the spring is going to accelerate it back again. it's just a badly-worded question.)

It leads right to misstatements like that[question].

We need more questions like:
"An insane tramp takes a snowboard to the top of the tallest hill in town. The hill is a 3:1 gradient and 20m in elevation. Assuming that the road surface is tarmac with a coefficiant of friction as given in Table 1, what speed does the tramp reach at the foot of the hill? How likely is the tramp to survive the collision 10m from the foot of the hill with a ten ton lorry loaded with razor blades? How likely is the tramp to quit halfway down and ask someone for money for a cup of tea?"
