A meter stick balances horizontally on a knife-edge at the 50.0 cm mark. With two 5.00 g coins stacked over the 12.0 cm mark, the stick is found to balance at the 43.0 cm mark. What is the mass of the meter stick?
Ok, phillip, jane, mark, john. Nothing irritates me more than some student posting a lot of homework or test questions under differing names. Why would a volunteer help someone trying to con them?
I will be happy to critique your thinking.
