two tains one travelling at `72kmh^(-1)` and other at `90 kmh ^(-1)` are heading towards one another along a strauight level track. When they are 1.0km apart, both the drivers simultanously see the other 's train and apply brakes which restard each train at the rate of `1 .0ms^(-2)`.determine whether the trains would collide or not.

Two trans one t ravelling at 54 kmph and the other at 72 kmph are headed towards one another along a straingt track. When they are 1//2 km apart, both drivers simultaneously seee the other train and apply their brakes. If each train is decelerated at the rate of 1 m//s^(2) , will there be a collision ?

Two trains, one travelling at 54 kph and the ot her at 72kph, are headed towards each ot her on a level track. When the yare two kilometers apart, both drivers simultaneously apply their brakes. If their brakes produces equal retardation in both the trains at a rate of 0.15 m//s^(2) , determine whether there is a collision or not

On a foggy day two drivers spot each other when they are just 80 meters apart. They are travelling at 27kmh^(-1) and 60kmh^(-1) , respectively. Both of them applied brakes retarding their cars at the rate of 5ms^(-2) Determine whether they avoid collision or not.

Two trains travelling along a straight track are heading towards each other, travelling at 90km/hr and 100km/hr. Drivers of both the trains apply brakes together when the train are 1.0km apart, decelerating each train at 2.0m//s^(2) . Determine that whether the train accident will be averted.

On a foggy day, the two cars are approaching each other on a straight road, with speeds 72 km h^(-10 and 54 km h^(-1) . The drivers of the cars spot other when they were 60 meres apart. Both of them applied brakes, retarding their cars at of 6 ms^(-1) . Predict whether they will avert collision or not.

Two trains, each travelling with a speed of 37.5kmh^(-1) are approaching each other on the same straingh track. A bird that can fly at 60 kmph flies off from one train when they are 90 km apart and heads directly for the other train. On reaching the other train, it flies back to the first and so on. total distance covered by the bird before trains collide is

Two trains, each with a speed of 50 kmph are headed towards each other on the same trake. A bird that can fly at the rate of 100kmph flies off one train when they are 100km apart and heads directly to the other train. On reaching the other train it flies back to the first train and so forth. (a) How many trips can the bird make from one train to the other before they crash ? (b) How is the total distance the bird travels ?

Two trains, each having a speed of 30 km/h, are headed at each other on the same track. A bird that can fly 60 km/h flies off the front of on train when they are 60km apart and heads directly to the other train. On reaching the train, the bird flies back to the first train. What is the total distance the bird travels before the train collide?

Two cars travelling towards each other on a straight road at velocity 10 m//s and 12 m//s respectively. When they are 150 metre apart, both drivers apply their brakes and each car decelerates at 2 m//s^(2) until it stops. How far apart will they be when they have both come to a stop?
