How Does Friction Impact Tug of War Dynamics?

[novawinters]

Homework Statement

In a game of tug of warcontest on a firm, horizontal sandy beach, Team A consists of six players with an average mass of 65 kg and Team B consists of 5 players with an average mass of 84 kg. Team B pulling with a force of 3200 , dislodges Team A and then applies good physics principles and pulls on Team A with a force of 2900 , just enough to keep Team A mov ing a at constant velocity. What is Team A's?
a. static friction
b. kinetic friction

Homework Equations

uS = Fs/Fn
uK = Fk/Fn

The Attempt at a Solution

Fn = Fg = mg
65 kg x 9.8N/kg
637 N
uS = 637 N/2900N
0.22
