Question

express 36 km-1 in m s-1​

Answer 1

Answer:

10 m / s

Explanation:

Given ,

speed = 36 km/hr

To find ,

speed in m /s

Solution :

speed = 36 km / hr

= 36 ×1000 / 60 × 60

= 1×1000 / 10 × 10

= 1000 /100 = 10 m / s ( Answer)

Extra :

1) speed = distance / time

=> s = d/t

2) Speed is scalar quantity ( a physical quantity having only magnitude & no direction ).

3) Its always +ve.

4) Its SI unit is m/s.
