Consider a gliding seed similar to that of alsomitra macrocarpa. the seed has a mass of 250 mg., a functional lift-to-drag ratio of 4.0, a lift coefficient under the same conditions of 0.3, and a wing area of 5000 mm2. the seed is released 15 m above the ground and reaches its final velocity essentially immediately. in still air. in still air, the velocity along the glide path is about:
a. 60 m
b. 6 m
c. 600m
