Rollerboards 2

In the figure below is shown one of the now common "rollerboard" suitcases on wheels first carried by airline flight crews. Suppose I've packed such a suitcase for a two-day trip. If it's lying in the position shown below, estimate how much force I would need to begin to tilt it upward onto its wheels using the handle. Be sure to clearly state your assumptions, since grading on this problem will be mostly based on your reasoning, not on your answer.
