Two balls of equal mass collide and stick together as shown in the figure. The initial velocity of ball B is twice that of ball A. (Take è = 34°.)
(a) Calculate the angle above the horizontal of the motion of mass A + B after the collision.
1 Units are required for this answer. 12.7 degree
(b) What is the ratio of the final velocity of the mass A + B to the initial velocity of ball A, vf/vA?
2

(c) What is the ratio of the final energy of the system to the initial energy of the system, Ef/Ei?
3
cannot_evaluate 0.65
Is the collision elastic or inelastic?
