At the end of the film Titanic, Rose was floating on a wooden door as shown below while Jack stayed in the icy cold water. Many people have questioned why Jack didn't also float on the door. In this problem, we will explore what might have happened. Suppose the door is 1.0 m wide and 2.0 m tall, and made of red oak (p = 740 kg/m³). Suppose Rose has a mass of 60 kg and Jack has a mass of 75 kg. 3. (a) If the door were floating by itself (with nobody on it), what fraction of the door would be submerged? (b) It appears that with Rose on top, about 2 cm of the door is above the surface of the water. What is the thickness of the door? (c) What is the maximum mass of people that can float on the door? Could Jack have joined Rose? (d) Suppose the door were made out of some other material. What is the maximum density that could support both Jack and Rose?

A host pours the remnants of several of wine into a jug a party. The host then inserts a cork with a 2.00-cm diameter into the bottle, placing it in direct contact with the wine. The host is amazed when the host pounds the cork into place and the bottom of the jug (with a 14.0-cm diameter) breaks away. Calculate the extra force exerted against the bottom if he pounded the cork with a 120-N force.
Bird bones have air pockets to reduce their weight—this also gives them an average density significantly less than that of the bones of other animals. Suppose an ornithologist weighs a bird bone air and in water and finds its mass is 45.0 g ad its apparent mass when submerged is 3.60 g (assume the bone is watertight.)(a) What mass of is displaced? (b) What is the volume of the bone? (c) What is its average density?
In an immersion measurement of a woman's density, she is found to have a mass of 62.0 kg in air an apparent mass of 0.0850 kg completely submerged with lungs empty. (a) What of water does she displace? (b) What is her volume? (c) Calculate her density. (d) If her lung capacity is 1.7S L, is she able to that without treading water with her lungs filled air?
You can break a strong wine bottle by pounding a cork into it with your fist, but the cork must press directly against the liquid filling the bottle—there can be no air between the cork and liquid. Explain why bottle breaks only if is no air between the cork and liquid.
In an immersion measurement of a woman's density, she is found to have a mass of 62.0 kg in air and an apparent mass of 0.0850 kg when completely submerged with lungs empty. (a) What mass of water does she displace? (b) What is her volume? (c) Calculate her density. (d) If her lung capacity is 1.75 L is she able to float without treading water with her lungs filled with air?
A 75.0-kg floats in freshwater 3.00% of his volume above water when his are empty, and 5.00% of his volume above water when his lungs are full. Calculate the volume of air inhales—called his lung capacity—in liters. (b) Does lung volume seem reasonable?
In Chapter 1.6 in the discussion of the hydrometer, it is stated: The higher the bulb floats, the greater the density of the liquid. Why is this? (See Fig. 1.14.)
Using the equation of the previous problem, find the viscosity of motor oil in which a steel ball of radius 0.8 mm falls a terminal speed of 4.32 cm/s. The densities of the ball and the oil are 7.86 and 0.88 g/mL, respectively.
The density of oil is less than that of water, yet a loaded oil tanker sits lower in the water than an empty one. Why?
