Question

A body is thrown vertically upwards and takes $5$ seconds to reach maximum height. The distance travelled by the body will be same in

• A. $1^{st}$ and $10^{th}$ second
• B. $2^{nd}$ and $8^{th}$ second
• C. $4^{th}$ and $6^{th}$ second
• D. Both (2) & (3)

Answer 1

Answer: (A)

The motion under gravity is a symmetric motion and the time taken to go up is same as time taken to come back to the initial position.

So, clearly the distance travelled in 1st second is same as that travelled in $10^{th}$ second
