Question

study the speed time graph of a car given above and answer the following questions :
1. what type of motion is represented by OA
2. what type of motion is represented by AB
3. what type of motion is represented by BC
4. what is the acceleration of a car from O to A
5. what is the acceleration of a car from A to B
6. what is the retardation of car from B to C​

Answer 1

Answer:

1.CONSTANT ACCELERATION

2.CONSTANT VELOCITY

3.CONSTANT RETARDATION

4.ACCELERATION=change in velocity/change in time (40/10=4m/s)

5.AS THE CAR MOVES WITH CONSTANT VELOCITY SO ACCELERATION IS (0) ZERO

6.RETARDATION GIVES NEGATIVE OF ACCELERATION (-40/20=-2m/s)
