Question

A girl walks along a straight path to drop
a letter box and dome back to her inital
position. Her displacement-time graph
is shown in fig 8.4. Plot a velocity-time
graph for the same.
​

Answer 1

Answer:

For the initial 50 second, velocity is 2 m/s. After that, velocity drops of zero, as shown by vertical line in graph.

For the next 50 second, velocity is taken in negative because displacement is becoming zero.
