Answer:
Momentum, p = 400 kg-m/s
Explanation:
Given that,
Mass of the football player, m = 100 kg
Velocity of the player, v = 4 m/s (towards north)
Let p is the momentum of the player. It is given by the product of mass and velocity of the object. Mathematically, it is given by :
p = m v
[tex]p=100\ kg\times 4\ m/s[/tex]
p = 400 kg-m/s
So, the momentum of the player is 400 kg-m/s. Hence, this is the required solution.
