SUMMARY

A 12 kg object with an initial kinetic energy of 24 joules will move 4 meters against a net resisting force of 6 Newtons. The work done by the resisting force, calculated as -24 joules, cancels out the object's kinetic energy, resulting in a distance of 4 meters before coming to a stop. This conclusion is based on the principles of work-energy, where the work done by the resisting force equals the initial kinetic energy of the object.

PREREQUISITES
  • Understanding of Newton's laws of motion
  • Familiarity with the work-energy principle
  • Basic knowledge of kinetic energy calculations
  • Ability to perform calculations involving force and distance
NEXT STEPS
  • Study the work-energy theorem in classical mechanics
  • Learn about calculating work done by constant forces
  • Explore real-world applications of kinetic energy in physics
  • Investigate problems involving friction and resisting forces
USEFUL FOR

Students preparing for physics examinations, educators teaching mechanics, and anyone interested in understanding the principles of motion and energy in physical systems.

A 12 kg object initally has 24 joules of kinetic energy. How far will the object move against a net resisting force of 6 Newtons? :rolleyes:

(A) 2 m
(B) 4 m
(C) 12 m
(D) 16 m
(E) 24 m

think its easy...

the mass is moving with a velocity 2m/s right?
the resisting force would so a work in such a way that the mass stops after moving a certain distance...so the work done by the resisting force should be cancelling out the mass's kinetic energy...the resisting force is constant throughout right?then the block would be moving 4 metres as then the 6 Newton force would be doing a work of -24 joules cancelling out the mass's kinetic energy...i think its right...what kind of a question is this...are u preparing for some entrance examination...nimmy try to bring in question which has more application...anyone can create high class questions which no one can even answer...so grab such questions which are made not for the sake of making questions...but ...i m just speaking out that's al...leave it
