A truck and car are moving on a plane road with same kinetic Energy. They are brought to rest by application of brakes which provide equal retarding forces. Which one of the following statements is true?
Answer & explanation
Correct answer: option 4
By work energy theorem we know :
KEf - KEi = Work done
So in this case : Initial KE = retarding force * distance traveled
Since kinetic energy is same and retarding force is equal distance traveled will be same
Hence choice (d) is correct
