Chapter 17, Problem 17.138RP

You are asked to analyze a catcher for a small drone. The catcher arm weighs 20 lb and is 8 ft long (you can model it as a slender rod); the net that catches the drone at B has negligible mass. The 3-lb drone has a mass moment of inertia about its own center of mass of 0.01 slug $\cdot$ ft². Knowing that the arm swings up to an angle of 30° below the horizontal, determine (a) the initial velocity v₀of the drone, (b) the forces at A at that angle.
