Question

A car travels 9 km towards southwards,followed by another 5 km southwards.What is the magnitude of its distance and displacement?​

Answer 1

Answer:

Explanation:

initial distance=u=9 km

final distance=v=5 km

∵ the car has travelled south ,it is facing south.

so, 5 km towards south is nothing but it travelled 5 km to north.

∴ distance travelled= v+u

                                = 9+5

                                = 14 km

now,displacement = v-u=9-5=4 km

Thus , magnitude of its distance and displacement is 14km and 4 km, resp.

Answer 2

Answer:

Both displacement and distance would have the same magnitude because the car is travelling in the same direction.

Therefore, The magnitude of distance and displacement = 9km + 5km

= 14km
