Question

A girls walks along a straight path to drop a letter in the letter box and comes back to her inetial position. Her displacement time graph is shown below S 100 a < 1 So - To Time (in sec) -> Findi I distance travelled 2 displacement of the girl 3 Velocity of the girl while going to drop the letter​

Answer 1

HOPE IT IS HELPFUL.

THANK YOU .

Answer 2

Answer:

As velocity time graph is a straight line, velocity of the girl is constant =displacement/time=100/50=2m/s.

Symmetry of displacement-time graph shows that the girl returns to her initial position with the same velocity in opposite direction. Therefore, velocity-time graph is as shown in Figure.

hope it helps u !!
