an airplane heads west at 400 miles per hour in a 50 mile per hour northwest wind. Find the ground speed and the bearing of the airplane

Suppose the skateboarder shown in the drawing reaches a height of 2.20 m above the right side of the semicircular ramp. He then makes an incomplete midair turn and ends up sliding down the right side of the ramp on his back. When the skateboarder reaches the bottom of the ramp, his speed is 6.20 m/s. The skateboarder's mass is 53.0 kg, and the radius of the semicircular ramp is 2.60 m. What is the average frictional force exerted on the skateboarder by the ramp?

If you found yourself on perfectly smooth ice in the center of a pond so that there was no friction, how could you get of the pond?

Two chambers are filled with a fluid. The ceiling of chamber 1 is at the same level as the floor of chamber 2. The pressure at the floor of chamber 2 is 1.7 × 105 Pa. If the area of the ceiling of chamber 1 is 2.0 m2, what is the magnitude F of the force exerted by the fluid on the ceiling of chamber 1?

Two liquids, 1 and 2, are in equilibrium in a U-tube that is open at both ends. The liquids do not mix, and liquid 1 rests on top of liquid 2. What is the ratio ρ1/ρ2 of the densities?

Three solid objects are floating in a liquid, as in the drawing. They have different weights and volumes, but have the same thickness (the dimension perpendicular to the screen). Rank the objects according to their density, largest first.

Blood flows through a section of a horizontal artery that is partially blocked by a deposit along the artery wall. As a hemoglobin molecule moves from the narrow region into the wider region, its speed changes from v2 = 0.800 m/s to v1 = 0.442 m/s. What is the change in pressure, P1 - P2, that it experiences? The density of blood is 1060 kg/m3.

Water is flowing down through the pipe shown in the drawing. Point A is at the higher elevation, while B and C are at the same elevation. The cross-sectional areas are the same at A and B. Rank the pressures at the three points, largest first.

Water is flowing down through the pipe shown in the drawing. Point A is 0.410 m higher than B. The speed of the water at A and B are vA = 5.00 m/s and vB = 2.78 m/s. Determine the difference PB - PA in pressures between B and A. The density of water is 1.00 × 103 kg/m3.

A Venturi meter is a device for measuring the speed of a fluid within a pipe. The drawing shows a gas flowing at speed v2 through a horizontal section of pipe whose cross-sectional area is A2 = 0.0777 m2. The gas has a density of ρ = 1.30 kg/m3. The Venturi meter has a cross-sectional area of A1 = 0.0233 m2 and has been substituted for a section of the larger pipe. The pressure difference between the two sections is P2 - P1 = 96.2 Pa. Find (a) the speed v2 of the gas in the larger original pipe and (b) the volume flow rate Q of the gas.
