An iceberg is floating in sea water. The iceberg has a height of 20 m and a cross-sectional area of 100 m^2. A certain amount of the iceberg is submerged.
a) Draw a picture of the problem. Label the forces on the iceberg
b) What is the sum of the forces on the iceberg in the y-direction?
c) Calculate the percentage of the iceberg, which is submerged through the sum of the forces. The density of seawater is 1024 kg/m^3. The density of fresh water (ice) is 917 kg/m^3.
d) As the climate gets warmer, 10% of the iceberg melts. How does the fraction of the iceberg submerged change?
