Dear Vishrant,

To find average velocity you need to find out the displacement.

so calculate the chord length from initial to final point ( after 2s)

u can calculate the chord length from the formula 2Rsin(c/2) where c is the angle subtended by the chord at the centre.

c=angular velocity x time

after that average acceleration is equal to average velocity by time
