<u>The magnitude of Vectors in Rectangular Form</u>
Given a vector v in its rectangular form:
The magnitude of v is:
We are given the vectors
Their magnitudes are:
Speed is defined as the distance over time. So in measuring the speed of a car, the most manual thing that we can do besides using a speedometer is to measure a certain distance then measure the time at which the car passes that distance then divide the distance over the time. Then determine the speed limit.
