During the first t seconds of motion, the average velocity of the point is zero. What is the numerical value of t?
The Attempt at a Solution
I don't understand this question. I understand that the average velocity is zero if the displacement in the denominator is zero. E.g. if a body is moving in a circle. Or if a body moves to the right and then to the left and distances cancel out. But how could you give the numerical value of t?
I thought t tended to zero (as a limit): 0.0000000001 but it is wrong.
Am I overlooking something obvious?
