Best ResponseYou've already chosen the best response.0joules are kg m^2/s^2 \[J/s= \frac{{kg}*m^2}{s^2}*\frac{1}{s}=\frac{{kg}*m^2}{s^3}\] Right?

Best ResponseYou've already chosen the best response.0Simply asking how to cancel out "s" in this situation.

Best ResponseYou've already chosen the best response.0Where are you canceling the s? Maybe with more context I can give you a better answer.

Best ResponseYou've already chosen the best response.0They don't cancel out. J/s = watts, and watts are kg m^2 / s^3, just like I showed above.

Best ResponseYou've already chosen the best response.0Remember, dividing by s is equivalent to multiplying by 1/s.

Best ResponseYou've already chosen the best response.0well, you know, the same well you can "remove" distance (m) in speed (m/s) to get time (t) by

Best ResponseYou've already chosen the best response.0d = vt m = (m/s)*(s) m = m But there's no cancellation in J/s...
