1. The problem statement, all variables and given/known data "Figure 5 depicts a 30 000 kg aircraft climbing at an angle θ = 15˚ when the thrust T = 180 kN. The aircraft’s speed is 300 km/hr and its acceleration is 2m/s2. If the radius of curvature of the path is 20 km (i.e., θ is decreasing), compute the lift and drag forces on the aircraft." a = 2m/s^2 T = 150000N Theta = 15 degrees Radius of Curvature (K) = 20000m v = 300km/hr => v = 83.3 m/s^1 2. Relevant equations W=mg, F=ma, a = v^2/K 3. The attempt at a solution I was going to treat this similar to an object moving up an inclined plane. Although, I don't know if this would work. I determined W = mg, W= 294,300N. I then thought using a = 83.3^2/20000 = 0.35 m/2^1. Therefore, F = ma, F = 30,000 * 0.35 = 10,500N. Therefore F + F(f) (i.e. Wsin(Theta)) = Drag. Upon calculating, I got close to the answer for drag but I believe only by coincidence. As I considered you would have to work out normal and tangential components individually, therefore a= v^2/K would be in the normal direction, not the tangential like I used it for. I also am unsure on how to calculate Lift if I cannot treat this an incline plane problem.
