Question

In Willy Wonka, the Ooompa-Loompas have to roll the blown-up Violet Beauregard to the juicing room 100 m down the hall. Starting from rest, they accelerate at a constant rate and arrive 2.0 minutes later. Violet rolls without slipping.

a.) Assuming her diameter is 1.6 m, how fast is Violet spinning when they arrive at the juicing room??

b.) Assuming her mass is 27 kg, what is her total kinetic energy? Approximate her shape to be a sphere.

*Moment of inertia for solid sphere: I=(2/5)MR^2
