radius - 70 m , then diameter - 2 into 70 - 140
time taken for 140 m half circle - 20
time taken for full circle - 20 into 2 - 40 sec
speed - distance upon time - 140 / 20 - 7 m/s
and if my answer is correct than click the thanks button

nikhil97:
What is displacement
displacement - velocity into time - 140 * 20 - 2800
Then what Is average velocity
average velocity

Here is your answer of (b)
Average velocity = distance/time
= 140/2
= 70 m/s
Average velocity = distance/time
= 140/2
= 70 m/s
it wrong as first we have to calculate the diameter and full time
