A bus moving on straight road comes to rest on applying breaks after travelling distance "d".If passengers add 80% weight to bus and travelling with same speed and braking force is same then find stopping distance of bus.

Retardation = Breaking force/Mass of bus =a
If initial velocity of bus is u and final velocity is v=0,
IF the passengers of the bus add to frictional force, it does not affect the distance d, but of they add to the braking force, then the distance d changes.
