Question

a car moving on a straight path covers a distance of 1 kilometre due to east in hundred seconds what is the speed and the velocity of the car​

Answer 1

Answer:

10 m/s

Explanation:

Speed = Distance Travelled/Time Taken to complete the distance

so

1 km/100s= 1 * 1000m/100s

= 10m/s

Velocity  = Displacement/Time

1 km/100 s= 1*1000m/100 s =10 m/s

And The direction of Velocity?

East

Answer 2

Question :

A car moving on a straight line path covers a distance of 1 kilometre due east in 100 seconds. What is the speed and the velocity of the car.

Answer:

Speed of the car is 10 m/s

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

Explanation:

(i) Speed :

Given:

Distance covered by the car = 1 km

Time taken = 100 seconds

Solution :

Speed = $\frac{Distance}{Time taken}$

Speed = $\frac{1 Km}{100 Seconds }$

Since time is in seconds, we have to convert the distance into metre.

So, 1km = 1000 m

Now,

Speed = $\frac{1000 m}{100 Seconds }$

Speed = 10 m/s

Therefore, The speed of the car is 10 m/s.

(ii) Velocity :

Given:

Distance covered by the car = 1 km

Time taken = 100 seconds

Speed = 10 m/s

Direction = East

Solution :

Velocity = The distance travelled per second by the body in a specified direction.

Velocity = Speed with the direction

Since the car is in one dimensional motion that is, moving along a straight line path, speed and velocity of the car are same.

Therefore, The Velocity of the car is 10 m/s due east.
