Heya frnd,
here is your answer,
In first 2 sec, displacement = 200cm
in next 5 sec, displacement = 200cm
total time = 2sec + 5sec = 7sec
total displacement = 200cm + 200cm = 400cm
as we know, velocity
= total displacement/ total time
= 400cm / 7sec
= 57.14 cm/sec
hence the velocity is 57.14 cm/sec
Hope this helps
if u need further help, just ask me i would like to help.
Thank you
