Question

20. 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 below figure. Plot a velocity-
time graph for the same.
→
100
Displacement (m)
0
50
Time (s) -
100​

Answer 1

Step-by-step explanation:

From the graph

(1) initial velocity, u=0

(2)velocity after 50s,v=displacement/time

V=100/5=2ms^-1

(3)velocity after 100s,V=displacement/time

V=0/100=0

Hope it is correct if yes then mark me brain list
