A seal with a mass of 130 kg floats on a slab of ice in the Arctic Ocean. What minimum volume must the slab have in order that the seal not get its skin wet with the seawater? In other words, the top surface of the ice slab is exactly at the same level as the seawater. Use 1025 kg/m3 for the density of seawater and 920 kg/m3 for the density of the ice slab. a) 1.24 m3 b) 1.01...

A Fisherman (100 kg) sitting on the ice notices that during the day the ice has become perfectly frictionless. Luckily the fisherman has caught 5 large fish (2 kg each) and knows he can throw some of them away in order to make it to the shore. Unluckily, a polar bear (200 kg) is approaching at 4m/s (I don’t know how he got started sliding, maybe he sneezed or flapped his ears). The fisherman can throw fish at 20m/s. a)     ...

A rectangular block of ice 13 m on each side and 1.1 m thick floats in sea water. The density of the sea water is 1025 kg/m3. The density of ice is 917 kg/m3. 1) How high does the top of the ice block float above the water level? 2) How many penguins of mass 20 kg each can stand on the ice block before they get their feet wet?

The polar ice caps contain about 1.8 · 1019 kg of ice. This contributes essentially nothing to the moment of inertia of the Earth because it is located at the poles, close to the axis of rotation. (a.) Estimate the change in the length of the day to be expected if the polar ice caps melt, distributing the water uniformly over the surface of the Earth. The moment of inertia of a thin spherical shell of mass m and radius...

A bathysphere used for deep-sea exploration has a radius of 1.50 m and a mass of 1.23 ✕ 104 kg. In order to dive, this submarine takes on mass in the form of sea water. Determine the amount of mass that the submarine must take on if it is to descend at a constant speed of 1.20 m/s, when the resistive force on it is 1095 N in the upward direction. Take 1.03 ✕ 103 kg/m3 as the density of...

A movie stuntman (mass 80.0 kg) stands on a window ledge 5.0 m above the floor (Figure 1) . Grabbing a rope attached to a chandelier, he swings down to grapple with the movie's villain (mass 70.0 kg), who is standing directly under the chandelier. (Assume that the stuntman's center of mass moves downward 5.0 m. He releases the rope just as he reaches the villain.) Part A With what speed do the entwined foes start to slide across the...
