Calculate the average force F acting on car

Click For Summary
SUMMARY

The average force F acting on a car that performs work Wcar = 5.9 x 10^5 J while traveling a distance of x = 6.3 km (6300 m) at constant speed is calculated using the formula Work = Force x Distance. The correct calculation yields F = Wcar / x, resulting in an average force of 93.65 N. The initial miscalculation of 3717 N was due to incorrect application of the formula and reliance on a calculator without proper verification.

PREREQUISITES
  • Understanding of basic physics concepts such as work and force.
  • Familiarity with the formula Work = Force x Distance.
  • Ability to perform unit conversions (e.g., kilometers to meters).
  • Proficiency in algebra for solving equations.
NEXT STEPS
  • Review the principles of Newton's laws of motion.
  • Study the concept of work-energy theorem in physics.
  • Learn about unit conversions and their importance in physics calculations.
  • Practice solving problems involving average force and work with different scenarios.
USEFUL FOR

Students studying physics, particularly those focusing on mechanics, as well as educators looking for examples of work and force calculations.

Calculate the average force F acting on car

Homework Statement



A car does the work Wcar=5.9x105 J in traveling a distance x=6.3 km (6300 m) at constant speed.

Calculate the average force F (from all sources) acting on the car in this process.

Homework Equations



Work = Force x Distance = F [tex]\Delta[/tex]x

The Attempt at a Solution



Since W=F[tex]\Delta[/tex]x
W=F/x

so F=5.9x10^5 J / 6300 m = 3717 N

Which is wrong. Not sure what else i could do. I'm not given any information other than supplied.
 
Physics news on Phys.org


It's wrong because i was being lazy and used the calc on the computer...

Anyway answer is 93.65
