Unformatted text preview: c) The total kinetic energy of the system is zero. d) You cannot say anything about the total kinetic energy of the system. 3. [5 points] Two balls approach each other from opposite directions with the same speed of 6.0 m/s and scatter elastically. One ball has three times the mass of the other ball. The lighter ball scatters at an angle of 90.0, the heavier one scatters at an angle = 35.3. What is the speed of the heavier ball after the collision? a) 4.00 m/s. b) 4.33 m/s. c) 4.66 m/s. d) 4.90 m/s 1 1 2 2...
