Answer 1

(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

2

(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
