#### Answer:

The tangential acceleration is

#### Explanation:

Assuming that the particle starts from rest

The initial angular velocity is

The radius of the circle is

The final velocity of the particle is

The final angular velocity is

The angle is

Applying the equation

Where

The tangential acceleration is
