AIPMT MAINS 2011 Physics Average Speed MCQ Question
Type: MCQ-numerical-Medium-Class 11
A particle covers half of its total distance with speed v₁ and the rest half distance with speed v₂. Its average speed during the complete journey is
A
v₁v₂² / (v₁² + v₂²)
B
(v₁ + v₂) / 2
C
2v₁v₂ / (v₁ + v₂)
D
2v₁v₂ / (v₁ + v₂)
Correct Answer
Option D
Detailed Explanation
The average speed is calculated as the total distance divided by the total time. For equal distances, the average speed is 2v₁v₂ / (v₁ + v₂).
