Rotational Mechanics

Classical Mechanics Level 1

Particle $A$ in the diagram moves along the circumference of a circle of radius $r=10\text{ cm}$ so that its radius vector relative to $O$ rotates with constant angular velocity $0.2 \text{ rad/s}.$

Find the absolute value of the particle's velocity $($ in $\text{cm/s})$ and the absolute value and direction of its acceleration $\big($ in $\text{cm/s}^2\big).$
