SUMMARY

The conversion of 8.4 meters per second squared (m/s²) to kilometers per hour squared (km/h²) requires careful attention to unit squaring. The correct formula is 8.4 m/s² multiplied by (1 km/1000 m) and (3600 s/1 h)². This results in a final value of 108,864 km/h², highlighting the importance of correctly applying unit conversions, especially with squared time units.

The question is to convert:
8.4 m/s^2 into km/h^2
I did:
8.4m/s(1000km/1m)(3600s/1h)= Wrong.
lol So what didn't I do right? I cancled out the m and s for km and h but according to my book this is wrong?
Thanks

The units of time are squared, so you might need to take that into account with your time conversion.
 
8.4 m/s^2 into km/h^2
8.4m/s^2(1km/1000m)(3600s/1h)^2
=8.4*3600*3600/1000
=8.4*3.6*3600
=30.24*3600
=108864 km/h^2
 
Pencil I believe that your probleme (aside from the squares) was that 1000m=1km and not 1000km=1m.
 
Oh! lol I'm so slow. Thanks all, I get it now.
 
The book claims the answer is that all the magnitudes are the same because "the gravitational force on the penguin is the same". I'm having trouble understanding this. I thought the buoyant force was equal to the weight of the fluid displaced. Weight depends on mass which depends on density. Therefore, due to the differing densities the buoyant force will be different in each case? Is this incorrect?
