Aporsche sports car can accelerate at 8.8 m/s^2. determine its acceleration in km/h^2.

The acceleration expressed in the new units is

Explanation:

To convert from to it is necessary to remember that there are 1000 meters in 1 kilometer and 3600 seconds in 1 hour:

Then by means of a rule of three it is get:

Hence, the units of meters and seconds will cancel. Notice the importance of square the ratio 3600s/1h, so that way they can match with the other units:

So the acceleration expressed in the new units is .
