Two ladders at the ends of a scaffold support a mass of 90.0 kg each. An 80.0kg worker is on the scaffold with a pile of bricks. Find the mass of the bricks.
I know the answer is 100 kg, but my problem is:
Two ladders which support the ends of a scaffold support 100.0 kg each. A 75.0kg worker is on the scafoold with a pile of bricks. Find the mass of the bricks in kg.
the answer is supposedly 125 kg, how did they get that answer?

Best ResponseYou've already chosen the best response.0The ladders support 200 kg total. 200 kg  75 kg = 125 kg I guess if the scaffold itself is massless :/
