Question

A car moving on a straight path covers a distance of 1 km due to east 100 sec find speed and velocity of car

Answer 1

Distance = 1km=1000m
time=100sec
speed=
$\frac{d}{s}$
$\frac{1000}{100}$
speed=10m/sec

Direction= east
velocity=
$\frac{1000m \: in \: the \: east}{100}$
velocity of the car=10m/s in the east direction

Answer 2

Answer:

Car acquires a distance of 1 km which is = 1000m

In 100 seconds

So, we can conclude that , distance = 1km (or) 1000 m and time = 100 seconds

Speed = ?

Velocity = ?

Therefore, we have to find the speed and velocity of the car

$speed \: \: = \frac{distance}{time}$

$speed \: = \: \frac {1000}{100 \: } \: = 10 \: ms {}^{ - 1}$

$\therefore \: Speed = 10ms {}^{ - 1}$

$velocity = \frac{distance}{time}$

$veovcity \: = \: \frac{1000}{100 \: } \: = 10ms {}^{ - 1}$

$\therefore \: Velocity = 10ms {}^{ - 1}$

Explanation:

Speed:

The speed of a body is the rate of change of distance with time.

Velocity:

The velocity of a body is the distance travelled per second by the body in a specified direction.
