Document Summary
Score: 18 pts. possible: zero, less than mv, zero, 4. 0 cm/s, 5. 0 cm/s, 6. 0 cm/s, 10. cm/s, 25 cm/s, equal to mv, greater than mv thin rod, about center: thin rod, about end: For multiple choice questions, circle the one best answer or letter (unless more than one answer is asked for). Some moments of inertia: hoop or thin ring: solid cylinder or disk: solid sphere: (1 pt. each, unless otherwise specified: (2 pts. ) A 5. 0-kg mass traveling with velocity 10. cm/s to the right collides head-on with a 2. 0-kg mass traveling with velocity v2 to the left. In order for the stuck-together pair to have zero velocity after the collision, the speed v2 must equal: a spaceship with total mass m is drifting through space at a constant velocity v. a. If the spaceship suddenly explodes, the sum of the momenta of all the little pieces is b.
