SUMMARY
When an impulse is applied to one end of a uniform rod of mass m and length l floating freely in space, the center of mass of the rod moves with a velocity determined by the impulse's magnitude and direction. The angular velocity of the rod is also established immediately after the impulse, calculated using the moment of inertia of the rod. The absence of friction allows for pure translational and rotational motion without external resistance, leading to predictable kinematics based on classical mechanics principles.
