A train stopping at two stations 4 km apart takes 4 min on the journey from one of the station to the other. Assuming that it first accelerates with a uniform acceleration x and then that of uniform retardation y, prove that `1/x + 1/y = 2.`

A train stopping at two stations 4km apart 4 minutes on the journey from one of the station to the other. Assuming that it first accelerates with a uniform acceleration x and then with uniform retardation y, prove that (1)/(x)+(1)/(y)=2

Two stations A and B are 2km apart. A train moves at first with a uniform acceleration a_(1) and then with a uniform retardation a_(2) to travel the distance AB in 4 min.Then

A train stopping at two stations 2 km apart on a straight line takes 4 minutes for the journey. Assuming that its motion its uniformly accelerated and then unoformly retarded. If (1)/(x)+(1)/(y) = n , where 'x' and 'y' are the magnitudesof the acceleration and retardation respectively. find the value of n .

A train, initially at station A , starts its journey and eventually stops at station B after travelling a distance s . The first part of its journey is under uniform acceleration u and the later part under uniform retardation v . Show that the time taken for the journey is sqrt(2s((1)/(u)+(1)/(v))).

A train goes from rest to rest between two stations with uniform acceleration and retardation. Find the rato of maximum velocity of the average velocity.
