Q. A rectangular block of ice 14.0 m on each side and 1.4 m thick floats in sea water. The density of the sea water is 1025 kg/m3. The density of ice is 917 kg/m3.

How many penguins of mass 22.0 kg can stand on the ice before they get their feet wet?

Q. Two blocks with masses m1 = 17.3 kg and m2 = 98.6 kg, are free to move. The coefficient of static friction between the blocks is 0.62 but the surface beneath m2 is frictionless.

What is the least force F necessary to hold m1 against m2?
