A particle moves in a semi circular path AB of radius 5m with constant speed of 11s^-1.(adsbygoogle = window.adsbygoogle || []).push({});

What is its average acceleration:

I worked it out but it was wrong, what i did was:

average acceleration = average velocity / time and got 4.8ms^-2.

Someone help please?
