A thin rod of mass 0.650 kg and length 1.62 m is at rest, hanging vertically from a strong, fixed hinge at its top end. Suddenly, a horizontal impulsive force (15.21) N is applied to it. (a) Suppose the force acts at the bottom end of the rod. Find the acceleration of its center of mass. a = Î + (b) Find the force the hinge exerts. Î + (c) Suppose the force acts at the midpoint of the rod. Find the acceleration of this point. a = Î + Ĵ (d) Find the hinge reaction force. F = + (e) Where can the impulse be applied so that the hinge will exert no horizontal force? This point is called the center of percussion.
