Excercise 2
A container fell off a ship. It weighs 20 000kg and has a surface of 2x5m and a height of 3m. How deep will the container sink in the water? (ro water = 1000kg/m³)
The container will sink 1.333m into the water.
When the container floats it will need an upwards force of 20ton because it had a downwards force of 20ton.
=> 20 ton = 20.000dm³ water
=> 3x5=15m² => 20m³/15m² = 1.333m
