Question

. A girl walks along a straight path to drop a letter in the letterbox and comes back to her initial position. Plot a velocity-time graph for the same

Answer 1

Explanation:

Solution :

As velocity time graph is a striaght line, velocity of the girl is constant

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