A kite weighs 9.8N having an area of 1m square makes an angle of 7.5 degree to the horizontal
when flying in a wind at speeds of 35km/h. If the pull on the string attached to the
kite is 50N and is inclined to the horizontal 45 degree. Determine the lift and dras
coefficients. The density of air is 1.2kg/m3.
