Okay, I am really curious as to how you solve this question, I can't seem to figure it out. I am sure most of you will think it's a piece of cake, but I'm not a physics person at all :p If the suitcase was lifted 0.75 meters, how much force was required? (Hint: Use the equation for "work") But see, the equation for work is Work= force x distance...and so there is not enough information? I don't know, I just can't wrap my head around this one, I have been thinking about it for awhile, and now it's really bothering me. That would make my day if someone knew how to do it, thanks!
