A ball is thrown vertically up with a certain velocity. It attains a height of `40m` and comes back to the thrower. Then the `(g=10m//s^(2))`

A

total distance covered by it is `40 m`

B

total displacement covered by it is `80 cm`

C

total displacement is zero

D

the average velocity for round trip is non zero.

Text Solution

Verified by Experts

The correct Answer is:
C
Displacement `=0` (initial position = final position)
average velocity `=0` (Total displacement `=0`).
