when object comes back to initial position after travelling 90m in 15

1.	when object comes back to initial position after travelling 90m in 15 second its average velocity is
Answer» Answer :- Zero Explanation :- According to the given question, the object has travelled 90m in 15 SECONDS and came BACK to its INITIAL position. Average velocity is DEFINED as the total displacement in a given TIME interval. Here, displacement is equal to zero because the body has returned back to its initial position. So, in this case Average velocity = Displacement ÷ Time ⇒ Average velocity = 0 ÷ 15 ⇒ Average velocity = 0 Hence, the average velocity is zero.

Answer»

Zero

According to the given question, the object has travelled 90m in 15 SECONDS and came BACK to its INITIAL position.

Average velocity is DEFINED as the total displacement in a given TIME interval.
Here, displacement is equal to zero because the body has returned back to its initial position.

So, in this case

Average velocity = Displacement ÷ Time

⇒ Average velocity = 0 ÷ 15

⇒ Average velocity = 0

Hence, the average velocity is zero.
