A body is thrown upwards and reaches its maximum height. At that position:

1.	its velocity is zero and its acceleration is also zero.
2.	its velocity is zero but its acceleration is maximum.
3.	its acceleration is minimum.
4.	its velocity is zero and its acceleration is the acceleration due to gravity.

In the following velocity-time graph of a body, the distance and displacement traveled by the body in 5 seconds in metres will be, respectively:

1. 75, 115

2. 110, 70

3. 45, 75

4. 95, 55

Figure below shows the velocity-time graph. This graph tells us that the body is:

1. Starting from rest and moving with increasing acceleration

2. Moving with uniform speed.

3. Moving with uniform acceleration.

4. Moving with decreasing acceleration.

Among the four graphs shown in the figure, there is only one graph for which average velocity over the time interval \((0,T)\) can vanish for a suitably chosen \(T\). Select the graph.

1.		2.
3.		4.

A lift is coming from the 8th floor and is just about to reach the 4th floor. Taking the ground floor as the origin and positive direction upwards for all quantities, which one of the following is correct:

If in one-dimensional motion, instantaneous speed \(v\) satisfies \(0\leq v<v_0\), then:

A vehicle travels half the distance \(\mathrm{L} \) with speed \(\mathrm{v_1}\) and the other half with speed \(\mathrm{v_2},\) then its average speed is:
1. $\frac{{\mathrm{v}}_1+{\mathrm{v}}_2}{2}$

2. $\frac{2{\mathrm{v}}_1+{\mathrm{v}}_2}{{\mathrm{v}}_1+{\mathrm{v}}_2}$

3. $\frac{2{\mathrm{v}}_1{\mathrm{v}}_2}{{\mathrm{v}}_1+{\mathrm{v}}_2}$

4. $\frac{\mathrm{L}({\mathrm{v}}_1+{\mathrm{v}}_2)}{{\mathrm{v}}_1{\mathrm{v}}_2}$

The displacement of a particle is given by x = ${(\mathrm{t} - 2)}^2$ where x is in meters and t in seconds. The. distance covered by the particle in the first 4 seconds is

1. 4 m
2. 8 m
3. 12 m
4. 16 m

At a metro station, a girl walks up a stationary escalator in time ${\mathrm{}}_{}$\(t_1\). If she remains stationary on the escalator, then the escalator takes her up in time \(t_2\). The time taken by her to walk upon the moving escalator will be:
1. \( \left(\mathrm{t}_1+\mathrm{t}_2\right) / 2\)
2. \( \mathrm{t}_1 \mathrm{t}_2 /\left(\mathrm{t}_2-\mathrm{t}_1\right)\)
3. \( \mathrm{t}_1 \mathrm{t}_2 /\left(\mathrm{t}_1+\mathrm{t}_2\right) \)
4. \( \mathrm{t}_1-\mathrm{t}_2\)
