Answer:
For train A, the initial
velocity,
Final velocity, and time,
Foe time B, Speed-time
graph for train A and B are shown in the figure.
Distance travelled by train
A = Area under straight line graphs RS
= Area of AORS
Distance
travelled by train B = Area under PQ=Area of AOPQ
Thus, train B travelled farther after the brakes were applied.
