A

total distance covered by it is `40m`

B

total displacement covered by it is `80m`

C

total displacement is zero

D

the average velocity for round tip is zero

Text Solution

Verified by Experts

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