SATHEE: Kinematics Question 344

Kinematics Question 344

Question: A body moves in straight line with velocity $v_{1}$ , for 1/3rd time and for remaining time with $v_{2}$ find average velocity.

Options:

A) $\frac{v_{1}}{3} + \frac{2 v_{2}}{3}$

B) $\frac{v_{1}}{3} + \frac{v_{2}}{3}$

C) $\frac{2 v_{1}}{3} + \frac{v_{2}}{3}$

D) $v_{1} + \frac{2 v_{2}}{3}$

Show Answer

Answer:

Correct Answer: A

Solution:

$V_{a v} = \frac{v_{1} t / 3 + v_{2} (2 t / 3)}{t} = \frac{v_{1}}{3} + \frac{2 v_{2}}{3}$
