$${{\pi }^{2}}\text{m}{{\text{s}}^{-2}}$$ and direction along the radius away from the center.

TuteeHUB · Answer

$${{\pi }^{2}}\text{m}{{\text{s}}^{-2}}$$ and direction along the radius towards the center.

TuteeHUB · Answer

$${{\pi }^{2}}\text{m}{{\text{s}}^{-2}}$$ and direction along the tangent to the circle.

TuteeHUB · Answer

$${{\pi }^{2}}\text{/4m}{{\text{s}}^{-2}}$$ and direction along the radius towards the center.
