A long thin bar (length L = 18 cm, mass 1.8 kg) of uniform density is placed upon a horizontal, frictionless surface. A small rubber puck (mass 250 g) slides towards the bar with a speed (2 m/s) directed perpendicular to the bar. It collides perfectly elastically with the bar at a distance (d) from the center of mass of the bar in such a way that the puck rebounds with a velocity (1 m/s). a) What is the value...
