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.8.4.
Plot a velocity–time graph for the same.
From the graph, we have:
Initial velocity (u) = 0
Now, Velocity(v) = displacement/time
Therefore, the velocity after 50s =?
v = 100/50 = 2ms-1
Ans, the velocity after 100s,
Here, the displacement = 0
Then, time = 100s
velocity=displacement/time
V = 0/100 = 0
V | 0 | 2 | 0 |
T | 0 | 50 | 100 |
Velocity – time graph plotted from the above data is:
