Question

A car moving in a straight path cover a distance of 1 km due east in 100 s. what is (i) the speed and (ii) the velocity of car

Answer 1

Here, distance travelled is 1 km, that means 1000 m Time is 100 s

The formula for speed is distance divided by time, that is 1000 by 100, So the speed is 10 m/s

As the car is travelling in east side, it can be said that the velocity of the car is 10 m per s towards the east side.

Answer 2

As we know that

1) S=d/t

=1km/100s

=1km=1000m

=1000m/100s

=10m/s

2)v=displacement /time

=1000/100

=10m/s due east
