This is for the extension section of my course. There are similar questions I have to do. Can anyone please help me on how to do this question so I can solve similar questions?Thanks
I would start by determining where x will be for t = 0, -1, and -1/2. Presumably you see that x will lie on the line AB; knowing these three points will guide you in answering the questions. (One of them will be A, one will be B, and another will be somewhere else -- as you can tell from the options, it will be the point midway between them.)
Please tell us what you find, and what your conclusions are, so we can help if you are wrong.
I hope you see that 2x= A + B means that x is the midpoint of AB. Do you?
You know that when t = -1, x = A. You can see by example (and can prove) that when t increases above -1 (e.g. -1/2, 0), x is moving toward B, right? So what is the set of all x for t > -1? Which of the four figures is this?
