The location of a particle is changed. What can we say about the displacement and distance covered by the particle?

 1 Both cannot be zero. 2 One of the two may be zero. 3 Both must be zero. 4 If one is positive, the other is negative, and vice-versa.

A drunkard walking in a narrow lane takes $$5$$ steps forward and $$3$$ steps backward, followed again by $$5$$ steps forward and $$3$$ steps backward, and so on. Each step is $$1$$ m long and requires $$1$$ s. There is a pit on the road $$13$$ m away from the starting point. The drunkard will fall into the pit after:
1. $$37$$ s
2. $$31$$ s
3. $$29$$ s
4. $$33$$ s

The figure shows the displacement-time graph of a particle moving on the x-axis. Then,

 1 the particle is continuously going in a positive x-direction. 2 the particle is at rest. 3 the velocity increases up to a time $$t_0$$, and then becomes constant. 4 the particle moves at a constant velocity up to a time $$t_0$$, and then stops.

A car moves from $$\mathrm{X}$$ to $$\mathrm{Y}$$ with a uniform speed $$\mathrm{v_u}$$ and returns to $$\mathrm{X}$$ with a uniform speed $$\mathrm{v_d}.$$ The average speed for this round trip is:

1. $\frac{2{\mathrm{v}}_{\mathrm{d}}{\mathrm{v}}_{\mathrm{u}}}{{\mathrm{v}}_{\mathrm{d}}+{\mathrm{v}}_{\mathrm{u}}}$

2. $\sqrt{{\mathrm{v}}_{\mathrm{u}}{\mathrm{v}}_{\mathrm{d}}}$

3. $\frac{{\mathrm{v}}_{\mathrm{d}}{\mathrm{v}}_{\mathrm{u}}}{{\mathrm{v}}_{\mathrm{d}}+{\mathrm{v}}_{\mathrm{u}}}$

4. $\frac{{\mathrm{v}}_{\mathrm{u}}+{\mathrm{v}}_{\mathrm{d}}}{2}$
