quick and correct solution please.
Please use the Rigid Bodies method from vector dynamics.
The small spheres, which have the masses and initial velocities shown in the figure, strike and become
attached to the spiked ends of the rod, which is freely pivoted at O and is initially at rest. Determine
the angular velocity w of the assembly after impact. Use v = 2 m/s, a = 0.2 m, and b = 0.3 m.
Neglect the mass of the rod. (w = 10.9 rad/s)
