A particle is moving along a circular path of radius \( 5 \mathrm{~m} \) with a uniform speed \( 5 \mathrm{~ms}^{-1} \). What is the
\( \mathrm{P} \) magnitude of average acceleration during the

W interval in which particle completes half revolution?
(1) \( 10 / \pi \mathrm{ms}^{-2} \)
(2) \( 20 / \pi \mathrm{ms}^{-2} \)
(3) \( 10 \mathrm{~ms}^{-2} \)
(4) \( 40 / \pi \mathrm{ms}^{-2} \)
