Answer
The correct answer is:
(a) zero
Work Step by Step
The correct answer is:
(a) zero
The magnitude of the average velocity is the absolute value of the average velocity which is: $v_{ave} = \frac{displacement}{total~time}$
In this case, the displacement is zero and the total time is $\Delta t$
Therefore, the average velocity is $\frac{0}{\Delta t} = 0$
The magnitude of the average velocity is zero.
