Centripetal Force, very simple.

Click For Summary
SUMMARY

The discussion focuses on calculating the centripetal force required for a partner weighing 475 N, moving in a circular path with a radius of 6.50 m at a speed of 4.00 m/s. The formula used is F = mv²/r, where the calculated centripetal force is 1,169 N. However, it is emphasized that this value does not account for the gravitational force acting on the partner, which must also be considered in the final calculation.

PREREQUISITES
  • Understanding of centripetal force and its calculation using F = mv²/r
  • Knowledge of gravitational force and its impact on objects in circular motion
  • Basic algebra skills for manipulating equations
  • Familiarity with units of force (Newtons)
NEXT STEPS
  • Review the concept of gravitational force and its calculation
  • Learn about the relationship between centripetal force and gravitational force in circular motion
  • Explore examples of centripetal force in real-world applications
  • Study the effects of varying radius and speed on centripetal force
USEFUL FOR

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

Homework Statement



A man hanging upside down is holding a partner who weighs 475 N. Assume that the
partner moves on a circle that has a radius of 6.50 m. At a swinging speed of 4.00 m/s,
what force must the man apply to his partner in the straight-down position?

Homework Equations



F=mv^2/r

The Attempt at a Solution


I just plugged in the numbers and got 1,169. Is it correct?

Hi nothing4me! :smile:

That's the correct centripetal force, but you still have to deal with the gravitational force. :wink:
