The figure shows the velocity (v) of a particle plotted against time (t).

The figure shows the velocity (v) of a particle ploted against time (t).

The figure shows the v - t graph of a particle moving in a straight line. Starting from rest, the time after which the particle returns to its starting position is

The figure shows the v - t graph of a particle moving in a straight line. Starting from rest, the time after which the particle returns to its starting position is

Figure shows the velocity time graph of a particle moving along straight line (v is m/s and t is in second). It average velocity in 20 seconds will be: .

Figure shows the velocity time graph of a particle moving along straight line (v is m/s and t is in second). It average velocity in 20 seconds will be: .

For a particle moving in a straight line, the position-time graph is as shown in the figure. Find the velocity of the particle at time t=1 s and t=4 s . Also sketch the v-t graph.
