railway RRB Technician Grade 3 Mock Test 2024 Physics Motion in a Straight Line Average velocity and average speed
Ramesh travels on a straight path with uniform velocity V1 for some time and with uniform velocity V2 for the next equal time.
The average velocity v of Ramesh is
1
v = \(\sqrt{v_1v_2}\)
2
\(\frac{1}{v}=\frac{1}{v_1}+\frac{1}{v_2}\)
3
\(v=\frac{v_1+v_2}{2}\)
4
\(\frac{2}{v}=\frac{1}{v_1}+\frac{1}{v_2}\)
