Question

I am trying to answer this question and am unsure of what to do with the units- do i square the (m/s)?

1/2(6x10^4 kg)((200 m/s)^2)

Answer 1

i think what should really be written is:
\[1/2(6x10^{4 }kg)((200 m/s^{2})\]

Answer 2

or if you write it in more cleare way:
\[6*10^{6} kg* m/s^{2}\]

Answer 3

\[K=1/2(6x10^{4})(200m/s)^{2}\] this is what it should be- sorry i have never used the site before and didnt know about the equation editor feature- how do i deal with the (m/s) with the squaring it

Answer 4

you have to square the units too:
\[(200m/s)^{2}=200^{2}m ^{2}/s ^{2}\]

Answer 5

thank you! so the final answer would be: \[1.2x10^{9} (kg)(m ^{2})/s ^{2}\] ??

Answer 6

i think you forgot to devide by 2

Answer 7

ohh never mind, ya you correct

Answer 8

thank you so much :D
