Question

a car moves hundred metre due east and then 25 due to West (a) what is the distance covered by the car (b)what is its displacement​

Answer 1

Answer:

The ans is

a) 125 meters

b) 75 meters

Explanation:

As the car traveled 100 meters and then 25 meters the total distance is 125 meters.

Now it moved 100 m from the initial position and came back towards it 25 m so the displacement is  75 m.

Answer 2

Answer:

Distance covered: 125 m. Displacement = 75 m

Explanation:

The answer is so because distance is a scalar quantity, it will be only influenced magnitude not by direction. So we add the distances travelled which is 100 + 25 = 125 m. On the other hand displacement is a vector quantity meaning it will be influenced by both magnitude and direction. When operating with a vector quantity case one direction is taken as positive similar to a number line. So the other direction becomes negative automatically. Here in this case the car travelled 100 m east and then 25 m west , so it will be 100 - 25 = 75. That's it.

Hope you like the answer.
