**Re: Physics/Math**

Calculate the ratio of the drag force on a passenger jet flying with a speed of 750 km/h at an altitude of 10 km to the drag force on a prop-driven transport flying at one-fifth the 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...

**math**

A jet is flying through a wind that is blowing with a speed of 45 mi/h in the direction N 30° E (see the figure). The jet has a speed of 775 mi/h relative to the air, and the pilot heads the jet in the direction N 45° E.
