Questions
A train is moving at a constant speed V when its driver observes another train in front of him on the same track and moving in the same direction with constant speed v. If the distance between the trains is x, then what should be the minimum retardation of the train so as to avoid collision?
detailed solution
Correct option is D
Here relative velocity of the train w.r.t other train is V - v. Hence, 0 - (V - v)2 =2axor a=−(V−v)22x Minimum retardation =(V−v)22xTalk to our academic expert!
