Homework Statement


A jet is refueled in mid-air by a tanker. The fueling boom enters the aircraft at an angle of 30 degrees from its flight path. The fuel flow rate is 20kg/s at a velocity of 30m/s with respect to the two aircrafts. The density of the fuel is 700kg/m^3
What is the additional lift needed to overcome the additional force?


Homework Equations


F= ma

The Attempt at a Solution


As Force is kg m/s^2, wouldn't the force be mass flow x velocity?
Then just do sin 30 to the force to get the y component.
But somehow I think I've got the wrong method...

Think about this in terms of momentum and impulse.
