a plane is flying with a constant speed along a straight line at an angle 60degree with the horizontal. the weight(W) of the plane is 90,000N and its engine provides a thrust(T)of 120,000N in the direction of flight . two additional forces are exerted on the plane :the lift force(F) perpendicular to the plane's wings and the force (R) due to air resistance opposite to the direction of motion . draw the free body diagram showing all the forces on the plane. determine F and R
