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

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 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.

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.

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?

Two trains A and B are approaching each other on a straight track, the former with a uniform velocity of 25 m/s and other with 15m/s, when they are 225 m a part brakes are simultaneously applied to both of them. The deceleration given by the brakes to thetrain B increases linearly with time by 0.3 m//s^(2) every second, while the train A is given a uniform deceleration, (a) What must be the minimum deceleration of the train A so that the trains do not collide ? (b) What is the time taken by the trains to come to stop ?

Two cars are travelling towards each other on a straight road at velocities 15 m//s and m//s respectively. When they are 150 m apart both the drivers apply the brakes and the car decelerate at 3 m//s^(2) and 4 m//s^(2) until they stop separation between the cars when they come to rest is

A driver travelling at 90 kph applied the brakes for 5 s. If the braking acceleration was 2 m//s^(2) , what was her final speed ?

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.
