PhysicsEasysingle choice

A uniform rod of mass $m$ and length $L$ is at rest on a smooth horizontal surface. A ball of mass $m,$ moving with velocity $v_{0},$ hits the rod perpendicularly at its one end and sticks to it. The angular velocity of rod after collision is

Options:

Answer:

Solution:

$m v_{0} \times (\frac{L}{4}) = (\frac{7}{48} m L^{2} + m \times \frac{L^{2}}{16}) \times ω$

$\Rightarrow ω = \frac{6 v_{0}}{5 L}$
