(i) What type of motion is represented by OA?
(ii) What type of motion is represented by AB?
(iii) Wht type of motion is represented by BC?
(iv) What is the acceleration of car from O to A?
(v) What is the acceleration of car A to B?
(vi) What is the retardation of car from B to C?
(i) Uniform acceleration is represented by OA.
(ii) Constant speed is represented by AB.
(iii) Uniform retardation is represented by BC.
(iv) the acceleration of car from O to A is 4 m/s2
(v) the acceleration of car A to B is Zero
(vi) the retardation of car from B to C is 2 m/s2.
