Miguel, the 72.0 kg bullfighter, runs toward an angry bull at a speed of 4.00 m/s. The 550 kg bull charges toward Miguel at 12.0 m/s amd Miguel must jump on the bull's back at the last minute to avoid being run over. What is the new velocity of Miguel and the bull as they move across the arena?

M1V1+M2V2=(M1+M2)V
solve for V 
M1V1+M2V2=(M1+M2)V
V1+V2=V
