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?

Matt is driving down 7th street. he drives 150 meters in 18 sec. assuming he doesn’t slow down or speed up, what is his speed?

Afisherman notices that his boat is moving up and down periodically without any horizontal motion, owing to waves on the surface of the water. it takes a time of 2.20 s for the boat to travel from its highest point to its lowest, a total distance of 0.670 m . the fisherman sees that the wave crests are spaced a horizontal distance of 5.80 m apart. (a) how much is the wavelength? (b) find the period of the wave. (c) how fast are the waves traveling? (d) what is the amplitude a of each wave?
