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 kmph and the other at 72 kmph are headed towards one an other along a straight track. When they are 1/2 km apart, both drivers simultaneously see the other train and apply their brakes. If each train is decelerated at the rate of 1 ms^(-2) , will there be collision ?

Two trains are travelling at 88m/s and the other at 117.3m/s are headed towards one another along a straight level track when they are 10560m apart , both engineers simultaneously see the other train and apply their brakes . If the brake deceleration each train at the rate of 3m/s_2 , determine whether they are in 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.

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
