hi

2. Algebraic! Group Title

$d= r \theta$

3. Algebraic! Group Title

$\frac{ 106 }{ .9} = \theta$

4. Algebraic! Group Title

convert theta to rev.s and use: $\omega _{f}^{2} =\omega _{i}^{2} +2\alpha \theta$ to find alpha

5. Algebraic! Group Title

then find time in minutes from: $\omega _{f} = \omega _{i} + \alpha t$
