The graph shows the time and velocity of a certain vehicle. Study the graph and answer the following questions:
a) Between which two points did the vehicle retain uniform velocity? b) At which point did the vehicle start moving and at which point did it stop? c) At which point did the retardation of vehicle start? d) Where did the vehicle have maximum acceleration and deceleration? e) Where did the acceleration of the vehicle retains zero?

Answer:
i) OA represents uniform acceleration
(ii) AB represents constant speed.
(iii) BC represents uniform retardation.
(iv) Acceleration of car from O to A= slope of line OA
a=
10−0
40−0
=4m/s

(v) Acceleration of car from A to B is zero as it has uniform speed during this time.
(vi) Retardation of car from B to C= slope of line BC
a=
50−30
0−40
=
20
−40
=−2m/s
