Question

8. A car moving on a straight road covers a distance
of 1.5 km due east in 150 s. What is the speed of
the car? What is its velocity?​

Answer 1

Answer:

velocity = displacement

____________

time

1.5

___

150

answer is 100

Answer 2

Answer: Speed = 10m/s

Velocity = 10m/s

Explanation:

Given,

Distance travelled by car = 1.5km

= 1.5 × 1000. ( 1km = 1000m )

= 1500m

Displacement = 1.5km due to east

Time = 150s

Therefore, A/q.

Case 1 -

Speed = Total distance travelled/Total time taken

= 1500m/150s

= 10m/s

Now,

Case 2-

Velocity = Displacement due to east/Time Taken ( Here Displacement = Distance )

= 1500m/150s

= 10m/s

Therefore, Speed = 10m/s

Velocity = 10m/s
