A car is travelling in the north direction. To stop, it produces a deceleration of 60 m/s2. Which of the following is a correct representation for the deceleration?
  • a)
    60 m/s2 Northwards
  • b)
    60 m/s2 Southwards
  • c)
    60 m/s2 Eastwards
  • d)
    60 m/s2 Westwards
Correct answer is option 'B'. Can you explain this answer?

Deceleration always acts in the direction opposite to the direction of motion. Magnitude of deceleration is 60 m/s2 and it acts in the direction opposite to North. Hence the answer is 60 m/s2 Southwards.

Deceleration of a car travelling northward

To understand the correct representation of the deceleration of a car travelling in the north direction, let's break down the given options and analyze them:

a) 60 m/s2 Northwards
This representation is incorrect as it redundantly states the direction of the deceleration (Northwards) along with the magnitude (60 m/s2).

b) 60 m/s2 Southwards
This is the correct representation for the deceleration of the car. When a car is travelling in the north direction and decelerates, it essentially starts moving towards the south direction.

c) 60 m/s2 Eastwards
This representation is incorrect as it mentions the deceleration in the east direction, which is not relevant to the scenario described.

d) 60 m/s2 Westwards
Similar to option c, this representation is also incorrect as it indicates the deceleration in the west direction, which is not applicable in this context.

Therefore, the correct representation for the deceleration of a car travelling in the north direction is option b) 60 m/s2 Southwards. This signifies that the car is slowing down and moving towards the south direction from its initial northward trajectory.
