Question

11. A train is running at a constant speed of 36 km h - Express its speed in m s. [Ans. 10 m s']
​

Answer 1

Step-by-step explanation:

Constant speed is 36 km/h

In m/s

= 36× 5/18

= 10

Answer is 10 m/ sec

hope it helps

Answer 2

Answer:

HLO DEAR

Step-by-step explanation:

Speed of train in km/h = 36 km/h

Speed of train in m/s = ?

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

time

distance

36 \: km \: { h}^{ - 1 } = \frac{36 \: km}{1h}36kmh

−1

=

1h

36km

= \frac{36 \times 1000m}{60 \times 60s}=

60×60s

36×1000m

= 10 \: ms {}^{ - 1}=10ms

−1

Therefore, Speed of train in m/s = 10 m/s

Explanation:

For a moving body, speed is the quantity by which we know how fast the body is moving.

By speed we do not know in which direction the body is moving.

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

Numerically it is the distance travelled by the body in one second.

It is a scalar quantity.

It is generally represented by the letter u and v.
