The variation of velocity of a particle with time moving along a straight line is illustrated in the following figure. The distance travelled by the particle in four seconds is 

1. 60 m

2. 55 m

3. 25 m

4. 30 m

The displacement of a particle as a function of time is shown in the figure. The figure shows that
                      
1. The particle starts with certain velocity but the motion is retarded and finally the particle stops
2. The velocity of the particle is constant throughout
3. The acceleration of the particle is constant throughout
4. The particle starts with constant velocity, then motion is accelerated and finally the particle moves with another constant velocity

A ball is thrown vertically upwards. Which of the following graph/graphs represent velocity-time graph of the ball during its flight (air resistance is neglected) 

1. a

2. b

3. c

4. d

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:

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. \(40~\text{m}\)
