Consider a gliding seed similar to that of Alsomitra macrocarpa (Fig. 12.11a, also p. 261). 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 mm^2. The seed is released 15 m above the ground and reaches its final velocity essentially immediately. a. In still air, what is the greatest horizontal distance it can go from the point of release? b. How long will it take to hit the ground? c. If the seed is released into a temporally steady, spatially uniform, horizontal wind of 5 m s-1, how far will it go, (i) gliding with the wind, and (ii) gliding into the wind? d. In still air, the velocity along the glide path is about?

1) (23.0 pts) A student in a physics class decides to test their understanding of Projectile Motion theory by determining how fast they throw a baseball. On a nice day, with essentially n wind, they go out to a park to perfonm the experiment. The student throws the baseball to get an idea of the angle at which they will launch the baseball. By using the idea that the length from the middle of one's chest to the finger tips...
Answer: 10.12 A key is dropped from a bridge that is 40.0 m bove the water. At the moment the key is released a model boat is 10.5 m away from the bridge and moving towards the bridge with constant velocity. If the key falls directly into the model boat, calculate the Velocity of the boat. Answer: 11. [2pt] Arie is aimed honuntaily a target located 345 m away. The ballet hits the target 25 cm below the aim point....
