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? |
Distance traveled by truck is shorter then car before coming to rest Distance traveled by car is shorter then truck before coming to rest Distance traveled depends on individual velocity of both the vehicles Both will travel same distance before coming to rest |
Both will travel same distance before coming to rest |
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 |
