Since we are discussing the questions. Here is one I can't forget, it was one of the tough Physics question in the year when I took JEE. Here goes (text from my memory): There is a rolled carpet of length, L, kept on an even floor. A person gives it a gentle push, and the carpet starts to unroll. What will be the velocity of the unrolled piece of the carpet, when the carpet is half unrolled? (You can ignore the contribution of the initial push, for this computation) PS: I will look for answers, here tomorrow ... :-)
