A runner, jogging along a straight line path, starts at a position 260 m east of a milestone marker and heads west. After a short time interval he is 120 m west of the mile marker. Consider east to be the positive x-direction.
(a) What is the runner's displacement from his starting point? Incorrect: Your answer is incorrect. m in the x-direction
(b) What is his displacement from the milestone? Incorrect: Your answer is incorrect. m in the x-direction
(c) The runner then turns around and heads east. If at a later time the runner is 330 east of the milestone, what is his displacement from the starting point at this time?
(d) What is the total distance traveled from the starting point if the runner stops at the final position listed in part (c)?
