Q. No.A car travels a distance \(AB\) in three equal segments: the first third at a velocity of \(v_1~\text{m/s},\) the second third at \(v_2~\text{m/s},\) and the final third at \(v_3~\text{m/s}.\) Given that \(v_3 = 3v_1 , ~v_2 = 2v_1\) and \(v_1 = 11~\text{m/s} ,\) the average velocity of the car is:
| 1. | \(12~\text{m/s}\) | 2. | \(18~\text{m/s}\) |
| 3. | \(16~\text{m/s}\) | 4. | \(11~\text{m/s}\) |

A car moving on a straight-line travels in same direction half of the distance with uniform velocity \(v_1\) and other half of the distance with uniform velocity \(v_2\) . The average velocity of the car is equal to:
1. \(\frac{2v_1v_2}{v_1+v_2}\)
2. \(\frac{v_1+v_2}{2}\)
3. \(v_1+v_2\)
4. \(\sqrt{v_1+v_2}\)
1. \(\frac{2v_1v_2}{v_1+v_2}\)
2. \(\frac{v_1+v_2}{2}\)
3. \(v_1+v_2\)
4. \(\sqrt{v_1+v_2}\)

An object travels a distance \(x\) with a constant speed \(v_1,\) and then covers another equal distance \(x \) with a different constant speed \(v_2.\) The average velocity \(v\) for the entire journey is given by:
| 1. | \(v=\left(\dfrac{v_1+v_2}{2}\right) \) | 2. | \(\dfrac{1}{v}=\dfrac{1}{v_1}+\dfrac{1}{v_2} \) |
| 3. | \(v=\left(\dfrac{2 v_1 v_2}{v_1+v_2}\right) \) | 4. | \(v=\left(\dfrac{v_1-v_2}{2}\right) \) |

A particle moving in a straight line covers half the distance with speed \(\begin{equation} 6 \mathrm{~m} / \mathrm{s} \end{equation}\). The other half is covered in two equal time intervals with speeds \(\begin{equation} 9 \mathrm{~m} / \mathrm{s} \end{equation}\) and \(\begin{equation} 15 \mathrm{~m} / \mathrm{s} \end{equation}\) respectively. The average speed of the particle during the motion is :
1. \(\begin{equation} 8.8 \mathrm{~m} / \mathrm{s} \end{equation}\)
2. \(\begin{equation} 8 \mathrm{~m} / \mathrm{s} \end{equation}\)
