According to Archimedes principle, the mass of a floating object equals the mass of the fluid displaced by the object. A 150 lb. swimmer is floating in a nearby pool; 95% of her body's volume is in the water while 5% of her body's volume is above water. Determine the density of the swimmers body. The density of water is 0.036lb/in^3.
A car accelerates uniformly rest to 81 ft/s over a distance of 700 ft along a curve of 800ft radius .Determine the magnitude of the total acceleration at the instant that speed of 81ft is reached.
