Problem III A ball of mass m is traveling to the left with speed vo before it collides elastically head-on with a ball of mass 3m that is initially at rest, hanging down from an ideal string of length L that is attached to the ceiling. The acceleration due to gravity is g and you may assume that the pendulum satisfies the small angle approximation. 16. The collision is: c. Elastic and one-dimensional d. Totally inelastic 17. The quantities conserved during the collision are: a. Only linear momentum b. Neither linear momentum nor mechanical energy c. Only mechanical energy d. Both linear momentum and mechanical energy 18. The velocity of the lighter ball right after the collision is: -Vo a. a. Elastic and two-dimensional b. Elastic but there is not enough information to determine if it is one or two- dimensional b. C. d. a. * SWINENTE 19. The velocity of the heavier ball right after the collision is: -Vo b. -Vo 3m vo 2 L Vo m y
