- A) determine the angular acceleration of the drum while the force is being applied. B) what was the net torque on the drum during this time?A particle of mass 0.300 kg is attached to the 100-cm mark of a meterstick of mass 0.150 kg. The meterstick rotates on the surface of a frictionless, horizontal table with an angular speed of 6.00 rad/s. a) Calculate the angular momentum of the system when the stick is pivoted about an axis perpendicular to the table through the 50.0-cm mark. b) Calculate the angular momentum of the system when the stick is pivoted about an axis perpendicular to the table through the 0-cm mark.A figure skater brings her arms up to her body A figure skater spins at angular speed rotation of 2 revolutions per second with its two perpendicular arms to his body: in this position, his moment of inertia is 3 kg.m^2. When she brings her arms to her body, its moment of inertia is only 1.5 kg.m^2: calculate its rotational kinetic energy in this position. (We neglects the friction between the runners and the ice.)
