1)What is the position vector r(t) as a function of angle $\theta \left(t\right)$. For later remember that $\theta \left(t\right)$ is itself a function of time.

Give your answer in terms of $R,\theta \left(t\right)$, and unit vectors x and y corresponding to the coordinate system in thefigure. 2)For uniform circular motion, find $\theta \left(t\right)$ at an arbitrary time t.

Give your answer in terms of $\omega$ and t.

3)Find r, a position vector at time.

Give your answer in terms of R and unit vectors x and/or y.

4)Determine an expression for the positionvector of a particle that starts on the positive y axis at (i.e., at ,$({x}_{0},{y}_{0})=(0,R)$) and subsequently moves with constant $\omega$.

Express your answer in terms of R, $\omega $ ,t ,and unit vectors x and
