An object with a mass of 0.020kg is moving at 80m/s when it slams into and sticks to the end of a thin rod that is fixed on the top of a table. The rod has a mass of 6.00 kg and a total length of 2.0m. The thin rod is free to rotate about its fixed axes. If the thin rod rotates about its centre (I=mL^2/12), what is its angular velocity right after the collision?
