Physics · Motion in one Dimension

NEET (UG) 2023 — Question 24

A vehicle travels half the distance with speed $\vartheta$ and the remaining distance with speed $2 \vartheta$ . Its average speed is:

Option A:
$\frac{2 \vartheta}{3}$
Option B:
$\frac{4 \vartheta}{3}$
Correct
Option C:
$\frac{3 \vartheta}{4}$
Option D:
$\frac{\vartheta}{3}$

Answer: B

Step-by-step solution

v_{\text {avg }} & =\frac{2 v_1 v_2}{v_1+v_2} \\ & =\frac{2 \times v \times 2 v}{v+2 v} \\ & =\frac{4 v}{3} \end{aligned}$$
