For a body projected vertically up with a velocity
from the ground, match the following.
Column-I | Column-II | ||
(A) | (Average velocity) | (I) | Zero for round trip |
(B) | (Average speed) | (II) | Over any time interval |
(C) | (III) | over the total time of its flight | |
(D) | (IV) | . |
Text Solution
Verified by ExpertsThe correct answer is:
C
For a round trip, displacement is zero; hence 
, when
is initial,
is final.
Hence
i, ii
Average speed
Hence
iii

Hence,
,
