Problem 7: A small light plane with a wing area of 150ft² is cruising at 120mph at 7000ft altitude. The airplane weighs 1600lb. Determine the lift coefficient. If the drag coefficient is 0.029, what is the drag force in pounds? The air density, p, at 7000ft altitude is 0.001927 slugs/ft³. (Hint: In level flight, assume lift equals weight.)
