Q7 of 58 Page 37

The following graph shows the motion of a car. What do you infer from the graph along OA and AB? What is the speed of the car along AB and what time it reached this speed

Along OA graph the car is going with constant acceleration


Along AB graph the car has constant speed and zero acceleration


Speed of the car is 70 along AB


Car reaches this speed between time interval 3 to 4
