Question

When average velocity is zero how to calculate the time taken?

Answer 1

Explanation:

Average speed is not necessarily the same as the magnitude of the average velocity, which is found by dividing the magnitude of the total displacement by the elapsed time. For example, if a trip starts and ends at the same location, the total displacement is zero, and therefore the average velocity is zero.

Answer 2

ANSWER:

U can use the formula.......
$s = ut + \frac{1}{2}a {t}^{2}$
