True False3) What is the torque applied to a wheel by a force of 0.2 N applied tangentially at a radius of 0.5 m? 10 m 1 m .1 m4) What is the moment of inertia of a disk of radius 0.10 m and mass 2.0 kg? 0.005 kg m^2 0.01 kg m^2 0.1 kg m^25) The initial angular velocity of an object is 2.0 rad/s, and the final angular velocity is 1.0 rad/s. If the initial moment of inertia is 0.5 kg m^2, what is the final moment of inertia, in the absence of net torques? 0.5 kg m^2/s 1.0 kg m^2/s 2.0 kg m^2/sHint Tweet
