Question

Convert a velocity of 36 km/hr into m/sec using dimemsional analysis

Answer 1

1 km/hr = 5/18 m/s
:. 36 km/ hr = 5/18 * 36 m/s
= 10 m/s [ ANSWER ]

Answer 2

Answer:

$36\: km/hr$

=$10m/sec$

Explanation:

Conversion of velocity :

$V = 36\: km/hr$

=$36 \times 1000m/60 minutes$

/* i)1km = 1000 m

i)1km = 1000 m ii ) 1hour = 60 minutes */

= $36\times 1000m/(60 \times 60 seconds)$

/* 1 minute = 60 seconds */

= $\frac{36000}{3600}m/sec$

After cancellation, we get

= $10m/sec$

Therefore,

$36\: km/hr$=$10m}/sec$
