Question

Wendy is walking along a trail. The trail heads east for 944 meters before turning south and continuing for 686 meters. At the end of the trail, what is Wendy's displacement vector? 1630m, 31.5° north of east 1167m, 36.0° east of north 1167m, 36.0° south of east 1630m, 31.5° east of north

Answer 1

Answer: 1167 m, 36 degrees South of East

Explanation: Using Pythagoras Theorem, 944 square + 686 square = resultant square, therefore, resultant is equal to 1167 meters. tan theta = perpendicular/base, therefore theta is equal to 36 degrees.
