a. 1

b. 2

c. 3

d. 1/2

e. 1/3

I say A becasue both add up to get the total kinetic energy.

**drwls**, Wednesday, April 22, 2009 at 3:53pmTranslational KE is (1/2) M V^2

Rotational KE is (1/2)I w^2

= (1/2) M R^2*(V/R)^2 = (1/2) M V^2

Your answer is correct but your reasoning is faulty. The ratio could be anything and they would still add up to give total KE
