The discussion focuses on calculating the resultant displacement of a man walking in various directions: 600m at [E47 degrees N], 500m at [N38 degrees W], 300m at [W29 degrees S], and 400m at [S13 degrees E]. The correct interpretation of the directional notation is clarified, specifically that [E47 degrees N] means measuring 47 degrees counterclockwise from the east axis. This understanding is crucial for accurately determining the resultant displacement using vector addition.
PREREQUISITESStudents studying physics, particularly those focusing on mechanics and vector analysis, as well as anyone interested in navigation and directional calculations.
PhanthomJay said:[E 47 degrees N] implies the angle is 47 degrees north of east , so, yes, you place the protractor's 0 degree mark at east, then measure up 47 degrees counterclockwise from the positive x (east) axis.
