A flywheel of radius 30 cm starts from rest and accelerates with constant with constant angular acceleration 0.5 `rad//s^(2)` . Compute the tangential , radial and resultant accelerations of a point on its circumference :
(a) initially at `theta = 0^(@)`
(b) after it has made one thrid of a revolution

Explanation

To solve the problem step by step, we will compute the tangential, radial, and resultant accelerations of a point on the circumference of a flywheel at two different instances: initially (at θ = 0°) and after it has made one-third of a revolution.

### Given Data:
- Radius of the flywheel, \( r = 30 \, \text{cm} = 0.3 \, \text{m} \)
- Angular acceleration, \( \alpha = 0.5 \, \text{rad/s}^2 \)
- Initial angular velocity, \( \omega_0 = 0 \, \text{rad/s} \)

### Part (a): At \( \theta = 0^\circ \)
