Assume a motion sensor is placed at the origin {i.e. position (x) = 0}. In each of the following problems, you will be given one of the following descriptions of motion: a written description, or a x versus t, a v versus t or an a versus t graph. Fill in/sketch the other threee descriptions of motion that would be consistant with the given one. Don't bother with exact numerical values, but make sure that (a) the sign (+/-) and...
