SUMMARY

The discussion focuses on the physics of friction in a tug of war scenario involving two teams on a sandy beach. Team A, with six players averaging 65 kg, experiences static friction calculated at 0.22 when Team B applies a force of 2900 N to maintain constant velocity. The calculations utilize the equations for static and kinetic friction, specifically uS = Fs/Fn and uK = Fk/Fn. The analysis highlights the importance of considering the total mass of Team A for accurate friction calculations.

PREREQUISITES
  • Understanding of basic physics principles, particularly Newton's laws of motion.
  • Familiarity with friction concepts, including static and kinetic friction.
  • Knowledge of force calculations involving mass and gravity.
  • Ability to apply equations related to friction, such as uS = Fs/Fn and uK = Fk/Fn.
NEXT STEPS
  • Study the effects of mass distribution on friction in competitive sports.
  • Explore advanced friction models beyond basic static and kinetic friction.
  • Learn about the role of surface materials in friction dynamics.
  • Investigate real-world applications of friction in engineering and design.
USEFUL FOR

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
