Two soccer players run toward each other. One player has a mass of 85 kg and runs west with a speed of 8 m/s, while the other has a mass of 105 kg and runs east with a speed of 7 m/s. What is the total momentum of the system made up of the two players?

Question

aravindg · Answer

Total momentum=m1u1+m2u2

Where m1,m2 are masses of first and 2nd bodies
u1,u2 are velocities of 1st and 2nd bodies

Make sure you use correct sign for velocity direction.
