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

A train starting from a railway station and moving with uniform acceleration attains a speed of 40km/hr in 10 minutes.Find its acceleration

A train starting from a railway station and moving with uniform acceleration attains a speed 40 km//h in 10 minutes. Find its acceleration.

The acceleration of a train between two stations 2 kilometre apart is shown in the figure. If train starts from rest than maximum speed of the train is

Two trains starting at the same time from two stations, 200 km apart and going in opposite directions, cross each other at a distance of 110 km from one of them. What is the ratio of their speeds?
