A 500g, 8.0-cm-diameter can rolls across the floor at 1.0 m/s. What's the can's kinetic energy.
I solved this using:
and for some reason I get 1/3 the answer. So I multiplied it by 3 at the end. Is there something wrong with the formula I'm using?
If i do the same thing with a similar problem I don't get the right answer. I think the difference lies in the 1.50 m/s.

Code:
K = [tex]\frac{1}{2}[/tex]*I*([tex]\frac{v}{r}[/tex])[tex]^{2}[/tex]
