1. If a slender bar rotates about end A, its angular momentum with respect to A is A) (1/12) m 1 o B) (1/6) m 1 o C) (1/3) m 1 o D) m 1 w 2. As in the principle of work and energy, if a force does no work, it does not need to be shown on the impulse and momentum diagram/equation. A) False C) Depends on the case. B) True D) No clue!! 3. Using conservation of linear and angular momentum requires that 1 G A) All linear impulses sum to zero. B) All angular impulses sum to zero. C) Both linear and angular impulses sum to zero. D) None of the above. A) IO. C) IG (m VG) + IGO. A 3 4. The angular momentum of a body about a point A that is the fixed axis of rotation but not the mass center (G) is B) IGO. D) Both A & C.
