A 90 cm rod of uniform density is placed on a fulcrum. a. If a mass of 0.5 kg is placed 20 cm away from the fulcrum, which itself is 10 cm away from the COG. what will be the mass of the meter stick. [10 pt] b. Using the mass of the meter stick (Mstick) calculated in (a), determine the unknown mass (m) if there is a 1 kg mass (M) placed 25 cm from the fulcrum, the fulcrum is 5 cm away from the COG and the position of the unknown mass is at the 65 cm mark.
