$4.)$ An airplane flies because of the lift force generated by the pressure difference between the top

and bottom of the wing. The mass of the airplane is $1353kg$ and the total area of the wings is

$16\mathrm{.}3m^2,$ This pressure difference is generated by the fact the air moves at different speeds

between the top and the bottom of the wing. The pressure difference produces the lift force

necessary to counterbalance the weight of the plane. The speed on the bottom of the wing is

$v_1=153\frac{m}{s}.$ Assume the height change of the wing is negligible. The density of air is $1\mathrm{.}29\frac{kg}{m^3}.$

a$.)$ Find the speed of air over the top of the wing, $v_2.$ See Diagram below.
