A 55.8 kg person skis down a 10 m tall hill. They start from rest at the top of the hill, but friction and air resistance both affect the skiers motion. If friction and air resistance have the effect of dissipating 1,027 J of energy away from the skier over the entire length of the hill, how fast are they traveling when they reach the bottom?

Oxygen-rich blood bound for the body tissues leaves the heart through the aorta, the major blood vessel emerging from the heart. It branches out to the arteries, which in turn branch into smaller vessels called arterioles (little arteries). These then branch into tiny, thin-walled capillaries. Blood travels slowly as the red blood cells squeeze through tiny capillaries. The radius of the aorta is approximately 9.8 mm and the speed of the blood there is 30 cm/s. A typical capillary has...

If a person drinks a large amount of water very quickly, it is possible to exceed the rate of water removal by the kidney (~1 L/hour), essentially diluting the blood. The resulting osmotic pressure causes cells to swell. Fat and muscle cells have a capacity to adjust to this change in volume, but neurons in the brain do not have room to accommodate this size increase. (The skull is so densely packed, there is no room for swelling!) Consequently, as...
