## Homework Statement

## Homework Equations

rotational kinetic energy = 0.5 I ⋅ M ⋅ ω², where I is the moment of intertia, M the mass and ω the angular speed

## The Attempt at a Solution

T = period of revolution

K = kinetic energy associated with rotational moviment

Since T increases with time according the text,

T = ƒ(t) = 3.31(10^-2) + 1.40(10^-14)

**t**

and I = 2K / ω²M = 2 ⋅ 5(10^31)

**t**/ [2π / [3.31(10^-2) + 1.40(10^-14)

**t**]² ⋅ 1.4(1.99)(10^30)]

I'm not sure about this answer. Could someone review it for me?
