# Circular Motion #3

A particle moves in a circular path of radius $$1$$. Its speed $$v$$, at time $$t$$ is given by $$v = 5 + 4 \sin ( \frac{ \pi }{ 6 } t )$$. What is the magnitude of the radial acceleration of the particle at $$t = 5$$?

The given information is in SI units. State your answer in SI units too.
