Question

an acceleration of 10m/s2 in km/h2​

Answer 1

Answer:

129600 km/hr2

Explanation:

1m = 1/1000 km &

1sec. = 1/3600 hr

so 10 m/s-2 = 10 * 1/1000 * (3600)2 km/hr2

129600 km/hr2

hope you got it

Answer 2

Acceleration in $km/h^2$ is $1.296\times10^5\ km\ h^{-2}$ .

Given :

Acceleration is $10\ m\ s^{-2}$ .

Therefore , $a=10\ m\ s^{-2}$    ......( 1 )

We need to convert it into $km\ h^{-2}$ .

We know ,

$1\ km=1000\ m\\ \\1\ m=10^{-3}\ km\ .$

And ,

$1 \ h=3600\ s\\\\1\ h^2=3600^2\ s^2\\\\1 \ s^{-2}=3600^2\ h^{-2}$

Putting value of $m$ and $s^{-2}$ in equation ( 1 ) we get ,

$a=10\ \times (10^{-3}\ km )\times(3600^2\times h^{-2})\\\\\a=1.296\times10^5\ km\ h^{-2}$

Hence , this is the required solution .
