Two rams run toward each other. One ram has a mass of 49 kg and runs west
with a speed of 7 m/s, while the other has a mass of 52 kg and runs east with
speed of 9 m/s. What will the momentum of the system made up of the two
ams be after they collide? Assume the total momentum of the system is
conserved.
A. 811 kg-m/s west
OB. 125 kg-m/s west
OC. 125 kg-m/s east
D. 811 kg-m/s east
