Question

If a ball is thrown up with a certain velocity. It attains a height of 40 m and comes back to the thrower, then

• A. Total distance covered by it is 40 m
• B. Total displacement covered by it is 80 m
• C. Total displacement is zero
• D. Total distance covered by it is zero.

Answer 1

The correct option is C Total displacement is zero

The ball thrown for height of 40m and comes back.

Hence $distance=40\left(up\right)+40\left(down\right)=80m$

$displacement=40\left(up\right)-40\left(down\right)=0m$
