Its length is 2 m and its mass is 10 kg, rotating at a rate of 20 rad/s. a) What is the rotational kinetic energy of the rod? {{youtube>gJdKzHawfgE?large}} ---- Part 2: b) A 3 kg mass is attached to the end of the rod. What is the rotational kinetic energy of this system? {{youtube>BShPtQbG0l0?large}} ---- Part 3: c) Someone throws a sphere (radius = 1 cm, mass = 5 kg) at the other end of the rod, where it sticks and deforms. What is the new moment of inertia? {{youtube>JanhFQSiZ2o?large}} === Four Quadrants === {{183_notes:examples:rotation_kinetic_energy_quadrant.png}} 183_notes/examples/videoswk10.txt Last modified: 2016/08/19 01:29by waterso8
