Question

when object comes back to initial position after travelling 90m in 15 second its average velocity is​

Answer 1

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.
