A particle starting from rest moves along the circumference of a circle of radius $$r$$ with angular acceleration $$\alpha$$. The magnitude of the average velocity, in the time it completes the small angular displacement $$\theta$$ is

$$r\left(\frac{2}{\alpha \theta}\right)^2$$

$$r\left(\frac{\alpha \theta}{2}\right)^2$$

$$\rho\left(\frac{\alpha \theta}{2}\right)$$

$$r\left(\frac{\alpha \theta}{2}\right)^{\frac{1}{2}}$$

A block of mass $$m$$ is moving on rough horizontal surface with momentum $$p$$. The coefficient of friction between the block and surface is $$\mu$$. The distance covered by block before it stops is [$$g=$$ acceleration due to gravity]

$$\frac{2 \mu M^2 g}{p^2}$$

$$\frac{p}{2 \mu M g}$$

$$\frac{2 \mu M g}{p}$$

$$\frac{p^2}{2 \mu M^2 g}$$
