Early college physics classes for me (got to do some more college a few years ago for fun) were pretty much built around these kinds of simplified riddles at first. If it doesn't give the info or ask to account for friction, don't. If it says the rope is put somewhere, assume that's where it stays unless the question requires it to move for what it asks. If it asks for the tension but doesn't give elasticity and such, then assume the rope stays still at the current length. If it asks you to find the gravitational attraction of a cow without giving a special definition shape, then assume it's a point mass. If it's not asking for relativity assume it's classical (hence point mass cows instead of the traditional spherical ones :D). And, of course, note any assumptions you do make while solving the problem so you might still get credit if they don't match the original intent.

Perhaps the funniest instance I remember is a problem about calculating time dilation in a plane. It gave all sorts of details and base information as one might want to expect (maybe even more)... except for the actual height above the surface, for which it was "at cruising altitude". I just wrote "assume 10 km altitude" and went from there.

I wouldn't define this a great benchmark by any means, rather just like the average early level college physics test vs "real" physics questions.
