Consider a train which can accelerate with an acceleration of `20cm//s^(2)` and slow down with deceleration of `100cm//s^(2)`. Find the minimum time for the train to travel between the stations 2.7 km apart. (180 s)

The acceleration of 20m//s^(2) in km //h^(2) is

The accelerator of a train can produce a uniform acceleration of 0.25ms^(-2) and its brake can produce a retardation of 0.5ms^(-2) The shortest time in which the train can travel between two stations 8 km apart is x minuts and 10 s, if it stops at both stations. The value of x is.

A bus can accelerate with an acceleration 1m//s^2 . Find the minimum time for the bus to reach the speed of 100 km/s from 50 km/s.

Convert an acceleration of 2km h^(-2) into cm s^(-2)

A man is 9 m behind a train at rest. The train starts with an acceleration of 2 "m.s"^(-2) and simultaneously the man starts running. He is able to board the train somehow after 3 s. Find the acceleration of the man.

A train is travelling at the speed of 90km/h. Brakes are applied so as to produce a uniform acceleration of 0.5m/ s^(2) . Find how far the train will go before it is brought to rest.

The greatest acceleration or deceleration that a train may have is a. The minimum time in which the train can get from one station to the next at a distance s is:
