Chapter 4: Particle Kinetics Homework Homework H4.S Given: Rigid arm OA (having length L and having negligible mass) is pinned to ground at end O. A particle of mass M is attached to end A of OA. At instant "1", a pellet P (having a mass of m) strikes the stationary particle A with a speed of up in the direction shown below in the figure. At the end of a short time interval impact, P sticks to A. Find: Determine the angular speed of arm OA immediately after P sticks to A. g L VP1 A M m P VERTICAL PLANE Use the following parameters in your analysis: = 30, L = 5 ft, mg = 4 lb, Mg = 8 lb and vp = 150 ft/s.
