SUMMARY

The discussion focuses on calculating the force required to move a 1750 kg elephant in a tug of war scenario against a 115 kg man, with a coefficient of friction of 1.0 for both. The initial calculation provided by a participant suggests a force of 1865 N, which is incorrect as it does not account for the frictional force acting on the elephant. To successfully move the elephant, one must consider the total frictional force, which is directly related to its weight. The conclusion emphasizes the need for a comprehensive understanding of the forces involved, including friction.

PREREQUISITES
  • Understanding of Newton's laws of motion
  • Knowledge of friction and its coefficient
  • Basic algebra for force calculations
  • Familiarity with weight and mass concepts
NEXT STEPS
  • Research the calculation of frictional force using the formula F_friction = μ * m * g
  • Study the implications of different coefficients of friction on movement
  • Explore the effects of weight on force requirements in physics
  • Learn about the dynamics of tug of war scenarios in physics
USEFUL FOR

This discussion is beneficial for physics students, educators, and anyone interested in understanding the principles of force, friction, and motion in practical scenarios.

Homework Statement


A very stong 115 kg man is having a tug of war with 1750 kg elephant. the coefficient friction for both on the groud is 1.o. a) find the force needed to move the elphant. b)
What would happen if the man could exert such a force

Homework Equations


F=w+a


The Attempt at a Solution


A)115kg+1750kg/1.0 =1865N
am i write?
B) the guy will probably die
am i right?

I think you might need to re think this slightly. Start by thinking about, or even better listing, all of the forces involved (all forces currently acting on the object you're interested in) and have a look in some textbooks or do an internet search to make sure you have all of the relevant (and correct) equations to solve the problem.

Once you have all of that you can start thinking about the additional force required (given the existing forces) to move the object.

In order to move the elephant you would need to overcome its friction. How is its friction related to its weight?
 
hint: what would happen on ice? :wink:
