The Attempt at a Solution
I have arrived on 3 solution that's seems to be logical to me but i don't know which is the correct one. Please help to explain to me which one is correct.
The first one is the water level will stay the same due to brick, boat and man already reflected in the water level. The water level is the same regardless if the brick is in the boat or water.
The second one is the water level will decrease. While the brick is still in the boat, the amount of water being displaced by the brick is equal the mass of the brick. When he chucks it in the water, the boat rises, as amt of water due to the mass of brick is no longer being displaced by the boat. When the brick is in the water,it displace less water because it sinks. Less water displaced by the brick means that there is a decrease in water level.
The last one is that the level of water will rise because an additional mass, which is the brick is introduced in the water.
Arghhhh too confusing alrdy. =(
