# Circular Motion #4

**Classical Mechanics**Level 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 tangential acceleration of the particle at \( t = 5 \)?

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