# Colliding Rod!

A uniform rod of length $$L = 3\text{ m}$$ and Mass $$M = 3.1565$$ is aligned with horizontal direction at an angle $$\theta = 37^\circ$$ at a height of $$H = 9.35\text{ m}$$ from horizontal. Now it is Released from that position . It collides with the sufficiently rough floor such that just after collision it's vertical velocity reduces to zero. Find the angular velocity ($$\omega$$) of the Rod just after collision .

Details And Assumptions:

• The ground is sufficiently rough to prevent slipping of contact point.

• Take $$g = 10\text{ m/s}^2$$.

• Initial height given is of centre of mass of rod from ground .

Hint: Get answer in variables first and then put data .
