A boy goes from A to B with a velocity of 20m/min and comes back from B to A with a velocity of 30m/min.The average velocity of the boy during the whole journey as: Option A:24m/minOption B:25m/minOption C:zeroOption D:20m/min.. About the author Quinn
Answer: option c: zero Explanation: Average velocity = [tex]\frac{Total displacement }{Total time}[/tex] Since in this case, the partial initial and final points are the same, therefore its displacement = 0 ∴Average velocity = 0 Reply
Answer:
option c: zero
Explanation:
Average velocity = [tex]\frac{Total displacement }{Total time}[/tex]
Since in this case, the partial initial and final points are the same,
therefore its displacement = 0
∴Average velocity = 0
