SUMMARY
Jim's net displacement after walking 100m south, 60m east, and 20m north can be calculated using the formula for displacement: d = √((x2-x1)² + (y2-y1)²). The net displacement magnitude is determined by the straight-line distance from the starting point to the endpoint. To express direction, one must calculate the angle of the resultant vector relative to the horizontal x-axis, which can be achieved through trigonometric functions.
