An unloaded bus can be stopped by applying brakes on straight road after covering a distance x. Suppose, the passengers add 50% of its weight as the load and the braking force remains unchanged. How long will the bus go, after the application of the brakes ? The velocity of the bus in both cases is assumed to be the same.
