When travelling freely a train is subjected to resistances which vary directly as the velocity and at 9= kph this is equal to 1 percent of the weight of the train. The brakes when applied create a further resistance equal to `l//16th` of the weight of the train. If the brakes are suddenly applied when the velocity is 90kph find the time and distance travelled before the train comes to rest.

1.	When travelling freely a train is subjected to resistances which vary directly as the velocity and at 9= kph this is equal to 1 percent of the weight of the train. The brakes when applied create a further resistance equal to `l//16th` of the weight of the train. If the brakes are suddenly applied when the velocity is 90kph find the time and distance travelled before the train comes to rest.
