Two wheels are connected by a belt that does not slip. The smaller wheel has a diameter D, while the bigger wheel has a diameter that is 4.00 times bigger. Calculate the ratio of the moments of inertia if the two wheels have: i) the same angular momentum about their rotation axes. ii) the same rotational kinetic energy.
Thank you. Shouldn't rotational kinetic energy be used, though, for part (b)?
Arithmetic question. Write only the final value of the answer. Suppose you did the rotational dynamics labs with a 200g solid sphere. The sphere was placed at rest at the 100cm mark on the track which is inclined at 150 angle with the table. What is the translational kinetic energy in (J) of the sphere as it leaves 0 mark of the track? Write your answer with TWO decimal places.
