The graph between the displacement \(x\) and time \(t\) for a particle moving in a straight line is shown in the figure.

During the interval OA, AB, BC and CD the acceleration of the particle is:

	OA	AB	BC	CD
1.	+	0	+	+
2.	–	0	+	0
3.	+	0	–	+
4.	–	0	–	0

The v – t graph of a moving object is given in the figure. The maximum acceleration is:
                             
1.  $1cm/se{c}^2$
2.  $2cm/se{c}^2$
3.  $3cm/se{c}^2$
4.  $6cm/se{c}^2$

The displacement versus time graph for a body moving in a straight line is shown in the figure. Which of the following regions represents the motion when no force is acting on the body?

1. ab

2. bc

3. cd

4. de

The $x-t$ graph shown in figure represents  

1. Constant velocity

2. Velocity of the body is continuously changing

3. Instantaneous velocity

4. The body travels with constant speed upto time t₁ and then stops

A lift is going up. The variation in the speed of the lift is as given in the graph. What is the height to which the lift takes the passengers?

The velocity-time \((v\text-t)\) graph of a body moving in a straight line is shown in the figure. The displacement and distance travelled by the body in \(6\) s are, respectively: 

1. \(8\) m, \(16\) m
2. \(16\) m, \(8\) m
3. \(16\) m, \(16\) m
4. \(8\) m, \(8\) m

Velocity-time \((v\text-t)\) graph for a moving object is shown in the figure. Total displacement of the object during the time interval when there is non-zero acceleration or retardation is:
                      
1. \(60~\text{m}\)
2. \(50~\text{m}\)
3. \(30~\text{m}\)
4. \(40~\text{m}\)

For the velocity-time graph shown in figure below the distance covered by the body in last two seconds of its motion is what fraction of the total distance covered by it in all the seven seconds 

1. $\frac{1}{2}$

2. $\frac{1}{4}$

3. $\frac{1}{3}$

4. $\frac{2}{3}$

In the following graph, the distance travelled by the body in metres is:

Velocity-time curve for a body projected vertically upwards is 

1. Parabola

2. Ellipse

3. Hyperbola

4. Straight line
