A man stands on a frictionless platform rotating with an initial angular velocity 4.0 rev/min. His arms are out and his rotational inertia is 5.00kg*m². He pulls in his arms reducing hos rotational inertia to 3.00kg*m^2

a) what is the initial angular velocity in rad/s?

b) what is his initial angular momentum?

c) what is his final angular momentum?

d) what is his initial rotational kinetic energy?

e) what is his final angular velocity in rad/s?

f) what is his final rotational kinetic energy?
