Q. The displacement of a particle as a function of time is shown in the figure. It indicates
- the particle starts with a certain velocity, but the motion is retarded and finally the particle stops.
- the velocity of the particle decreases.
- the acceleration of the particle is in opposite direction to the velocity.
- the particle starts with a constant velocity, the motion is accelerated and finally the particle moves with another constant velocity.

Q.
Figure 3.23 gives the x-t plot of a particle executing one-dimensional simple harmonic motion. (You will learn about this motion in more detail in Chapter14). Give the signs of position, velocity and acceleration variables of the particle at t = 0.3 s, 1.2 s, – 1.2 s.
