26. An automobile leaves St. John's University, first going due south at 88 km/h for 2

hours, and then turns on a road heading 20 degrees east of north at 55 km/h for 1.5

hours.

(a) Calculate the (x, y) components of the net displacement of the automobile from the

starting position, where the x-axis is east, and y-axis is north.

(b) Calculate the magnitude and direction of the automobile's net displacement. Given

the magnitude in km and its direction using points of the compass, like for example, "25

degrees east of north"
