Question

An object moves x distance with speed $v_1$ and next $x$ distance with speed $v_2$ . The average velocity $v$ is related to $v_1$ and $v_2$ as

A

$v = \frac{(v_1 + v_2)}{2}$

B

$\frac{1}{v} = \frac{1}{v_1} + \frac{1}{v_2}$

C

$v = \frac{(2v_1 v_2)}{(v_1 + v_2)}$

D

$v = \frac{(v_1 - v_2)}{2}$

Answer

$v = \frac{(2v_1 v_2)}{(v_1 + v_2)}$

Explanation

Solution

The correct option is (C): $v = \frac{(2v_1 v_2)}{(v_1 + v_2)}$
