Hey,

Considering that the velocity of particle is uniform, then

When the particle completes half revolution change in velocity

Δv=[v−(−v)] = 2v m/s

Time taken to complete the half revolution is
t=πr/v sec

Thus, average acceleration =Δv/t=2v/(πr/v)

Avg. Acceleration is = 2vv/πr

Hope it helps!
