railway RRB Technician Grade 1 Mock Test 2024 Physics Motion in a Straight Line Average velocity and average speed
A vehicle travels half the distance L with speed V1 and the other half with speed V2, then its average speed is
1
\(\frac{V_1+V_2}{2}\)
2
\(\frac{2V_1+V_2}{V_1+V_2}\)
3
\(\frac{2V_1V_2}{V_1+V_2}\)
4
\(\frac{L(V_1+V_2)}{V_1V_2}\)
