Part A- The center of mass of a 1 kg meter stick is 25 cm from the fulcrum on the left side. On the right side a rock is 25 cm away from the fulcrum. The meter stick and rock balance each other.  What is the mass of the rock?______kg Part B- Two meter sticks are placed up against the wall. Meter stick 1 has a piece of clay placed at the top of it. Both meter sticks are then pushed so that they fall to the ground. It take longer for meter stick 1 ( the one with the clay) to reach the ground. The reason is due to rotational inertia. (True or False)
