Answer:. Speed = 10m/s

Velocity = 10m/s

Explanation:

Given,

Distance = 1.5km

= 1.5 × 1000. ( 1km = 1000m )

= 1500m

Time = 150s

Therefore, A/q

Speed = Distance/Time

= 1500m/150s

= 10m/s

Now,

Velocity = Displacement/Time. ( Here Displacement = Distance )

= 1500m/150s

= 10m/s

Therefore, Speed = 10m/s

And Velocity = 10m/s

Answer:

• Speed (s) of the car is 10 m/s.

• Velocity (v) of the car is 10 m/s due east.

Given:

1. Car covers a distance of 1.5 Km due east.

2. Time taken (t) = 150 seconds.

Explanation:

Case-1

Firstly converting the Distance into meters.

⇒ 1 Km = 1000 m

⇒ 1.5 Km = 1.5 × 1000

                = 1500 m

d = 1500 m.

From the formula we know,

Speed = Distance / time

Substituting the values,

⇒ s = 1500 / 150

⇒ s = 10

s = 10 m/s

Speed (s) of the car is 10 m/s.

Case-2

As the body is travelling in straight line path both distance & Displacement will be equal.

Firstly converting the Displacement into meters.

⇒ 1 Km = 1000 m

⇒ 1.5 Km = 1.5 × 1000

                = 1500 m

D = 1500 m.

From the formula we know,

Velocity = Displacement / time

Substituting the values,

⇒ v = 1500 / 150

⇒ v = 10

v = 10 m/s

We Know that the velocity is a vector quantity i.e. has both Magnitude and direction. We got the magnitude, and the direction is due east in which the car is travelling.

v = 10 m/s due east

Velocity (v) of the car is 10 m/s due east.
