The total momentum of the system is equal to 50 Kgm/s.
<u>Given the following data:</u>
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.

true ........i really dont kno but ok hope this helps
Answer:
5m/s^2 is the acceleration.
Answer:
For a body moving at a uniform velocity you can calculate the speed by dividing the distance traveled by the amount of time it took, for example one mile in 1/2 hour would give you 2 miles per hour. If the velocity is non-uniform all you can say is what the average speed is.
Answer:
6.65×10⁻⁷ s
Explanation:
Speed of light in water = Total distance traveled in water/time
c = d/t ....................... Equation 1
Where c = speed of the light pulse in water, d = distance traveled in water, t = time.
also
c = v/n ..................... Equation 2
Where v = speed of light in air, n = refractive index of water
Substituting equation 2 into equation 1
v/n = d/t
making t the subject of the equation,
t = nd/v.................. Equation 3
Given: 150 m.
Constant: n = 1.33, v = 3.0×10⁸ m/s
Substitute into equation 3
t = 1.33(150)/3.0×10⁸
t = 6.65×10⁻⁷ seconds.
Hence the time = 6.65×10⁻⁷ s
