velocity is​

Answer 1

Answer:

5. Starting from a stationary position, Rahul paddles his bicycle to attain a velocity of 6m/s in 30 seconds. Then he applies brakes such that the velocity of a bicycle comes down to 4 m/s in the next 5 s

6.Average velocity = displacement / total time taken

( since Uma goes and comes back again then the initial and final position will be the same. Hence, displacement will be 0 )

= 0/2 = 0 m/s
