Assume D=(1/2)CpAv^2 gves the drag force on a pilot plus ejection seat just after they are ejected from a plane traveling horizontally at 1200 km/h. Assume also that the mass of the seat is equal to the mass of the pilot and that the drag coefficient is that of a sky diver. Assume the pilot's mass is 66 kg and using ve- 60 m/s for a single sky diver estimate the magnitudes of (a) the drag force on the pilot + seat and (b) the
ratio of the horizontal ddeceleration to g both just after ejection. (The result of (a) should indicate an engineering requirement: The seat must include a protective barrier to deflect the initial wind blast way from
the pilot's head.)
