A boggy of uniformly moving train is suddenly detached from train and stops after covering some distance. The distance covered by the boggy and distance covered by the train in the same time has relation
Text Solution
Verified by ExpertsThe correct answer is:
B
Let ' a' be the retardation of boggy then distance covered by it be S . If u is the initial velocity of boggy after detaching from train ( i.e. uniform speed of train)
Time taken by boggy to stop
In this time t distance travelled by train 
Hence ratio
