Question:

Solve Prob. 18.23, assuming that the assembly is hit at B in a direction opposite to that of the z axis. Problem 18.23 Three slender homogeneous rods, each of mass m and length d, are welded together to form the assembly shown, which hangs from a wire attached at G. The assembly is hit at A in a vertical downward direction. Denoting the corresponding impulse by FΔt, determine immediately after the impact

(a) The velocity of the mass center G,

(b) The angular velocity of the assembly.
