A rod with mass M = 5.00 kg is at rest on a horizontal surface. One end of the rod is connected to a pivot that allows the rod to rotate around the pivot after a net external force is exerted on the rod. The distance from the pivot point to the end of the rod is L = 1.50 m. A lump of clay with mass m = 175 g is launched horizontally toward the free end of the rod, at a speed v = 4.00 m/s, as shown in the figure below. When the clay hits the rod, it sticks to it and the combined rod-clay system rotates about the pivot point. The friction between the rod and the surface is negligible; ignore air resistance • The moment of inertia for a thin rod that pivots about its end is 1/3ML? • The moment of inertia for a point particle is mr?, where "r" is the distance from the point particle to the axis of rotation Pivot - Rod Lump of Clay Find the angular momentum of the clay relative to the axis of rotation of the rod (the pivot point). Find the angular velocity of the clay-rod system after the collision. State the key physics principle or law that applies to this situation.
