The acceleration of a moving body can be found from:
1. Area under the velocity-time graph
2. Area under the distance-time graph
3. Slope of the velocity-time graph
4. Slope of the distance-time graph
A particle starts from rest. Its acceleration \((a)\) versus time \((t)\) is as shown in the figure. The maximum speed of the particle will be:
1. \(110~\text{m/s}\)
2. \(55~\text{m/s}\)
3. \(550~\text{m/s}\)
4. \(660~\text{m/s}\)
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
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 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 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?
1. | \(3.6~\text{m}\) |
