While exploring a cave, a spelunker starts at the entrance and moves the following distances. She goes 75.0 m north, 250 m east, 108 m at an angle 30.0? north of east, and 181 m south. Find the resultant displacement from the cave entrance. The figure below suggests the situation but is not drawn to scale. magnitude unit(s) direction ? south of east

Explanation / Answer

Resultant displacement is the shortest distance between the initial and final point which is
250 m + 108*cos(30)

250+ 1083/2

=343.531 m
