Physics

Kat:

So I'm trying to find the PE (potential energy) and this is the equation: (10-kg)(10m/s/s)(25-meters) (I don't like your little strokes) (m/s/s = m/s * 1/s = m/s²)
Am I just supposed to multiply all of that? Is there any sort of conversion going on here? Because, it DOES have to come out in Joules (J)
