**drwls**, Wednesday, January 12, 2011 at 1:43amThe maximum legal mass of a bowlng ball is actually 7.27 kg, but who's counting?

a) (1/2)MV ^2, of course

b) (1/2) I w^2

Use (2/5)M R^2 for the moment of inertia, I, and V/R for the angular velocity w.

You will get an expression in terms of M and V. R will cancel out.

c) Add the results of a and b

You should get (7/10)M*V^2
