Calculate the ratio of the drag force on a passenger jet flying with a speed of 950 km/h at an altitude of 10 km to the drag force on a prop-driven transport flying at halfthe speed and half the altitude of the jet. At 10 km the density of air is 0.38 kg/m3 and at 5.0 km it is 0.67 kg/m3. Assume that the airplanes have the same effective cross-sectional area and the same drag coefficient C. (drag on jet...

In downhill speed skiing a skier is retarded by both the air drag force on the body and the kinetic frictional force on the skis. Suppose the slope angle is θ = 32.5°, the snow is dry snow with a coefficient of kinetic friction μk = 0.0400, the mass of the skier and equipment is m = 78.5 kg, the cross-sectional area of the (tucked) skier is A = 1.30 m2, the drag coefficient is C = 0.150, and the...

1. A rocket is launched vertically from the Earth, and the thrust (pushing force) from the engines is directed upward, and has a magnitude of 5.00 x 106 N. The mass of the rocket is initially 2.00 x 105 kg. (a) What is the initial acceleration of the rocket, assuming you can neglect air resistance? (b) After the rocket has been in flight for a while, burning and exhausting a lot of fuel, its mass has decreased to 1.20 x 105 kg, and...

Lecture I1.3. Drag Force 267 26 percent of greenhouse gas emissions come from cars, with a typical passeng emitting about 4.7 metric tons of carbon dioxide per year. Assuming all of the rom overcoming air resistance (ignoring internal resistances and stopping/starting much would we need to reduce the 70 mph speed limits vehicle emissions are how to obtain a 20 percent cut in greenhouse er emissions from cars? 14. A small particle with a radius of 0.1 mm and drag...
