A person travels along a straight road for the first half time with a velocity `v_1 `and the next half time with a velocity `v_2` . The mean velocity V of the man is

A

`2/v = (1)/(v_1) + (1)/(v_2)`

B

`V = (v_1 + v_2)/(2)`

C

`V = sqrt(v_1v_2)`

D

`V = sqrt(v_1/v_2)`

Text Solution

Verified by Experts

The correct Answer is:
