The total momentum of the system is equal to 50 Kgm/s.
<u>Given the following data:</u>
- Mass 1 = 80 kg
- Velocity 1 = 2 m/s east.
- Mass 2 = 70 kg
- Velocity 2 = 3 m/s west.
To determine the total momentum of the system:
Mathematically, momentum is given by the formula;
<u>For Football player 1:</u>
Momentum 1 = 160 Kgm/s.
<u>For Football player 2:</u>
Momentum 1 = 210 Kgm/s.
Now, we can calculate the total momentum of the system:
Total momentum = 50 Kgm/s.
<u>Note:</u> We subtracted because the football players were moving in opposite directions.
