Question
Two car A and B are moving on a road. A is speeding up while B is slowing down. Which of the following is correct about them?
- A is accelerating and B is retarding
- B is accelerating and A is retarding
- Both A and B are accelerating
- Both A and B are retarding
Hint:
Acceleration is of two types. Acceleration is velocity divided by time.
The correct answer is: Both A and B are accelerating
A is accelerating as it is speeding up and B is retarding as it is slowing down.
Accelerating means the car will cover a given distance in lesser time and retarding means the speed of the car is slow. Thus, A will cover any distance in lesser time than B.
