If a whale swims due east for a distance of 7.4 km, turns around and goes due west for 3.1 km and then turns around again and heads 3.6 km due east how do you figure out the total distance traveled by the whale?
Hello and thank you for posting your question to Brainmass!
the distance is the magnitude of the displacment vector (this means displecment has a direction as well as magnitude). When we have several consecutive displacements, the total distance is the *simple addition* of all the magnitudes of the different displacement ...
