All the structures specified are symmetric bodies with uniform mass density. For all these bodies, their centre of mass will lie in their geometric centres.

Not necessarily, the centre of gravity of a circular ring is at the imaginary centre of the ring.

The position vector of 1kg object is $\vec{r} = (3 \hat{i} - \hat{j}) m$ and its velocity $\vec{v} = (3 \hat{j} + \hat{k}) m s^{- 1} .$ The magnitude of is angular momentum is $\sqrt[]{x} N m$ where x is________.

$\overset{?}{L} = \overset{?}{r} * m \overset{?}{v}$

= $(3 \hat{i} ? \hat{j}) * (3 \hat{j} + \hat{k})$

$= 9 \hat{k} + 3 (? \hat{j}) ? \hat{i}$

$= ? \hat{i} ? 3 \hat{j} + 9 \hat{k}$

$| \overset{?}{L} | = \sqrt[]{1 + 9 + 81} = \sqrt[]{91}$

The angular speed of a fly wheel moving with uniform angular acceleration changes from 1200rpm to 3120 in 16 seconds. The angular acceleration in $r a d / s^{2}$ is:

$\begin{array}{r} ω = ω_{0} + α t \\ α = \frac{ω - ω_{0}}{t} \\ = \frac{(3120 - 1200)}{16 s} r p m \\ = \frac{1920}{16} \times \frac{2 π}{60} r a d / s^{2} \\ = 4 π r a d / s^{2} \end{array}$
