Question 23

A bus carrying extra passengers has a mass that is 40% greater than before. At its original speed, the bus stops under a constant braking force that is unchanged by the extra passengers. Its braking distance when carrying the extra passengers is 28 m.

What was the bus's braking distance before it carried the extra passengers?
