A plane is flying with a constant speed along a straight line at an angle of 30 deg. with the horizontal.The weight W of the plane is 80,000 and its engine provides a thrust T of 100,000N in the direction of flight.Two additional forces are exerted on the plane:the lift force F perpendicular to the planes wings,and the force R due to air resistance opposite to the direction of the direction of motion.Determine F and R
