taken as 0.015. Determine the average thickness of water
layer existing between the skater and the skating surface.

A frequently quoted rule of thumb in aircraft design is that wings should produce about 1000 N of lift per square meter of wing. (The fact that a wing has a top and bottom surface does not double its area.) a. At takeoff, an aircraft travels at 55 m/s, so that the air speed relative to the bottom of the wing is 55 m/s. Given the sea level density of air to be 1.29 kg/m3, how fast must it move over the upper surface to create the ideal lift? b. How fast must air move over the upper surface at a cruising speed of 249 m/s and at an altitude where air density is one-fourth that at sea level?
A typical hot air balloon can carry 3–5 passengers in a wicker basket and has a total mass of m = 470 kg including passengers, not including the mass of air inside the balloon. The density of hot air inside the stationary balloon is ?hot = 0.960 kg/m3 and the density of the cooler outside air is ?cool = 1.22 kg/m3. Determine the volume of hot air required for the balloon to be in equilibrium so that it neither sinks nor rises in the air.
Part A - A cube of volume 3.0 ×10-3 m3 (3.0 L) is placed on a scale in air. The scale reads 267 N. What is the material? Answers: Copper, ρ = 8.9 × 103 kg/m3 Aluminum, ρ = 2.7 × 103 kg/m3 Gold, ρ = 19 × 103 kg/m3 Lead, ρ = 11 × 103 kg/m3 Part B - An aluminum block of volume 200 × 10-6 m3 is held by a string at rest in oil as shown. ρAL = 2700 kg/m3, ρoil = 900 kg/m3, and g = 10 m/s2.
