B. 16 m/s at 76° with respect to the original direction of the lighter car
C. 11 m/s at 76° with respect to the original direction of the lighter car
D. 26 m/s at 76° with respect to the original direction of the lighter car
E. 16 m/s at 14° with respect to the original direction of the lighter car
