Answer:
[tex]f=431.69\ N[/tex]
Explanation:
Given:
- mass of the player, [tex]m=88.1\ kg[/tex]
- coefficient of kinetic friction between the ground and the player, [tex]\mu_k=0.5[/tex]
- Since the normal reaction force on the player due to its mass will be equal to the weight of the player.
We have the expression of kinetic friction as:
[tex]f=\mu_k.N[/tex]
here:
N = normal reaction force
[tex]f=0.5\times (88.1\times 9.8)[/tex]
[tex]f=431.69\ N[/tex]
