While John is traveling along a straight interstate highway, he notices that the mile marker reads 247 km. John travels until he reaches the 137 km marker and then retraces his path to the 164 km marker.
What is John’s resultant displacement from the 247 km marker?
What is final position-initial position? 164-247 km?
-83
To determine John's resultant displacement from the 247 km marker, we need to consider his initial position (247 km marker) and his final position after retracing his path (164 km marker).
The resultant displacement can be found by calculating the difference between the final position and the initial position. In this case, it would be:
Resultant displacement = Final position - Initial position
Substituting the values:
Resultant displacement = 164 km - 247 km
To find the resultant displacement, we need to subtract 247 km from 164 km.
Resultant displacement = -83 km
Therefore, John's resultant displacement from the 247 km marker is -83 km. The "negative" sign indicates that he is 83 km behind the initial position.
