A train covers 50 meter distance and stops when applied the breaks. If the velocity of train is just doubled and applied the same retarding force then the distance covered by the train is
Text Solution
Verified by ExpertsThe correct answer is:
D
Case- I 
V 2 = u 2 – 2as
a = 
Case- I 
0 = (2v) 2 – 2aS'
S' = 
= 
⇒ S' = 200 m
