Question

Can rotational kinetic energy be converted to translational kinetic energy

Answer 1

this hint is sufficient.

modify your formula by these general formula

here, k=radius gyration

Answer 2

Answer:

(a) Calculate the rotational kinetic energy of Earth on its axis. ... (a) Calculate the angular velocity the flywheel must have to contain enough energy to take the bus from rest to a speed of 20.0 m/s, assuming 90.0% of the rotational kinetic energy can be transformed into translational energy.
