A girl walks along a straight path to drop a letter in the letterbox and comes back to her initial position. Her displacement-time graph is shown in Fig. Plot a velocity - time graph for the same.
A girl walks along a straight path to drop a letter in the letterbox and comes back to her initial position. Her displacement-time graph is shown in Fig. Plot a velocity - time graph for the same.
For the initial $50\,\sec $, velocity is $2 \,m/s$. After that, velocity drops of zero ; as shown by vertical line in graph.
For the next $50\,\sec $, velocity is taken in negative because displacement is becoming zero.
