Aboeing 777 lands at chicago o'hare airport (668 m elevation) where the pressure is 98.8 kpa. this 777 wing has a coefficient of lift of 1.46, and its wing area is 4618.8 ft2 (this needs to be converted into m2). when the plane left st. louis, its mass was 225,982 kg. note that kilograms is mass not weight, so you need to convert it. during the flight to chicago, 7,534 liters of fuel was used, where the jet fuel weighs 0.781 kg/l. what is the velocity in miles-per-hour at the point where the aircraft initially touches the ground?

An charge with mass m and charge q is emitted from the origin, (x,y)=(0,0). a large, flat screen is located at x=l. there is a target on the screen at y position y(h), where y(h) > 0. in this problem, you will examine two different ways that the charge might hit the target. ignore gravity in this problem. 1.assume that the charge is emitted with velocity v(0) in the positive x direction. between the origin and the screen, the charge travels through a constant electric field pointing in the positive y direction. what should the magnitude e of the electric field be if the charge is to hit the target on the screen? express your answer in terms of m, q, y(h), v(0), and l. 2.now assume that the charge is emitted with velocity v(0) in the positive y direction. between the origin and the screen, the charge travels through a constant electric field pointing in the positive x direction. what should the magnitude e of the electric field be if the charge is to hit the target on the screen? express your answer in terms of m, q, y(h), v(0), and l.
