Question

Study the velocity - time graph of a travelling train as shown in the figure. Choose the correct labelling of the parts OA , AB and BC respectively.

1) OA --> uniform motion, AB --> Acceleration , BC --> Retardation
2) OA --> Acceleration , AB --> Uniform motion, BC --> Retardation
3) OA --> Retardation , AB --> Uniform motion, BC --> Acceleration
4) OA --> Acceleration , AB --> Retardation BC --> Uniform motion​

Answer 1

Answer:

2

Explanation:

as rate of change of velocity is acc in OA

and in AB vilocity is constant ie unifom motion

in BC portion velocity decreases with time ie deceleration
