A car travelling on a straight track moves with uniform velocity of v1 for some time and with uniform velocity v2 for the next equal time. The average velocity of the car is
- \(\frac{v_{1} v_{2}}{2}\)
- \(\frac{v_{1} v_{2}}{4}\)
- \(\frac{v_{1}+v_{2}}{2}\)
- \(\frac{v_{1}-v_{2}}{2}\)
Answer
(C) v_ 1 +v_ 2 2
